Version 3.0.1, August 22, 2016 - Download
- Implemented enum declarations.
- Implemented underscores in integer and floating-point literals.
- Implemented hexadecimal floating-point literals.
- Implemented binary integer literals.
Merged pull request #3: When adding an entry into
constant pool, it's index should be <= 65534, or <= 65533 if it's wide.
Major refactoring and simplification of the scanner; the "doc comment" and "expect greater" features were moved
to the parser (where they actually belong).
- Implemented the enum switch statement.
- Class literals in interface field initializers caused errors in the "flow analysis" phase.
IExpressionEvaluator: Marked the "ANY_TYPE" feature as deprecated.
It implements sort of an "autoboxing" mechanism, which is unnecessary since Java 5.
JSH: Added the "interactive mode", and thus moved the tool from project "commons-compiler" to project "janino",
because the specific parsing for interactive mode is only possible with a JANINO-dependent "StatementEvaluator"

Version 2.6.0, May 30, 2010 - Download
This version implements a number of incompatible changes:
CompileException was moved from package
org.codehaus.janino to package
org.codehaus.commons.compiler (and so were its buddies
ScanException were removed; all methods that previously threw
one or more of
CompileException. (This is an API simplification honoring the fact that applications
rarely want to differentiate between scan, parse and compilation problems).
The core functionality of JANINO (expression evaluator, script evaluator, class body evaluator, simple compiler
and Java source class loader) was extracted to new interfaces declared in the new package
org.codehaus.commons.compiler, while the original API remains unchanged.
A second implementation of the
org.codehaus.commons.compiler interfaces was added, based on the
javax.tools.JavaCompiler API that exists since JDK 1.6. This implementation is available in the
Rather than instantiating e.g.
org.codehaus.janino.ExpressionEvaluator directly, applications can now
which will use the first implementation of
IExpressionEvaluator on the class path (be it
commons-compiler-jdk.jar, or yet another implementation).
The JUNIT regression test suite was restructured so that if differentiates between implementation-independent tests,
which are automatically executed against every implementation on the class path, and implementation-specific tests.
Also, the following bugs were fixed:
- JANINO-143: java.lang.ClassFormatError: Duplicate method name&signature in class file Transformer1$1$1

two or three operands, "a.concat(b).concat(c)" is used as before.) Also, if
"java.lang.StringBuilder" (the unsynchronized brother of "StringBuffer") is available
(since JDK 1.5), it is used. See Tom Gibara's excellent
on his "String Concatenation Benchmark".

ScriptEvaluator with the capability to compile more
than one expression/script in one evaluator. This greatly improves the runtime performance and reduces the JVM
resource usage if you need to compile many expressions/scripts at the same time.
Introduced the concept of "auxiliary classes". This allows you to specify individual classes that the
expression/script/class body/compilation unit may access although they are not loadable through the
ClassLoader that was set with
setParentClassLoader(). In other words: The
expression/script/class body/compilation unit executes in a "sandbox", restricted by a
with minimal peepholes to the classes you specify. This also resolves issue JANINO-66: Security: restrict

Version 2.4.0, March 13, 2006 - Download
Major redesign of the
Java class hierarchy -- basically the "uplink" of the AST objects is no
longer set by a constructor parameter, but by the constructor of the superordinate AST object. As a
consequence, the creation order of AST objects is no longer top-down, but bottom-up. This makes code that
creates an AST significantly shorter.
UnitCompiler is now context-free, i.e. it can resolve types, constant values etc.
without compiling the unit. This is necessary for the upcoming
JGrep utility (see below).
Started work on the new
JGrep utility -- a command line tool that analyses a set of source files
in a highly configurable way.

Version 1.0.6, December 15, 2003
Added the "JavaSourceClassLoader" (requested by Richard Lewis 2003-11-14) and the "janino" utility that scans,
parses, compiles, loads and executes classes on-the-fly.

Version 1.0, October 20, 2003
Wow, version 1.0 finally made it. If you also feel that Janino 1.0 were a good reason to drink a glass of
champagne, do not hesitate. (Maybe, as a sign of recognition, you could send me the open bottle and I'll drink
it up ;-) My postal address is on janino.net)
Version 0.3.17, October 09, 2003 (not released)
Methods declared in interfaces of object were not found when invoked (reported by Fabrice Carnet 2003-10-07).
java.lang.VerifyError when loading a class compiled by Janino which invokes a method of an interface with more
than zero parameters (reported by Fabrice Carnet 2003-10-07).
ExpressionEvaluator, ScriptEvaluator and ClassBodyEvaluator now have constructors that allow for the
specification of class and/or method name (requested by Fabrice Carnet 2003-10-07).
Version 0.3.16, October 06, 2003 (not released)
Basically a complete rewrite of the IClass loading mechanism. This solves many problems related to using Janino
with custom ClassLoaders (e.g. in J2EE environments). (Reported by Laurent Millet 2003-09-24.)
Version 0.3.15, September 12, 2003
"net.janino.*Evaluator" now have constructor variants that allow the specification of extended / implemented
types. This allows for providing a base class that supplies static "helper functions" (e.g. "println()").
(Requested by Till Brychcy 2003-09-10.)
Version 0.3.14, July 27, 2003
- "net.janino.Compiler" can now compile a set of source files with forward references (requested by Richard Lewis 2003-07-24).
- Documented the "import" feature of ScriptEvaluator and ExpressionEvaluator.
- "Outer.Inner" was not properly resolved within ambiguous names.
Version 0.3.13, July 6, 2003
- Rewrote the "ClassBodyEvaluator"; can now be instantiated.
- "ClassBodyEvaluator" can now generate a class that extends / implements classes / interfaces (Requested by Richard Lewis 2003-06-28).
- Cleaned up "EvaluatorBase"; eliminating code duplicated between the various "*Evaluator" classes.
Version 0.3.12, June 4, 2003
- Fixed up method invocation conversion (reported by Antony Miguel 2003-06-02).
- Fixed a problem with for/while/do loops with constant true conditions. (Reported by Antony Miguel 2003-06-02).
- Made tons of methods and classes PUBLIC, as proposed by Antony Miguel 2003-06-03.
Version 0.3.11, June 1, 2003
- Implemented "synchronized" statement (requested by Antony Miguel 2003-05-22).
Moved common functionality from "ExpressionEvaluator", "ScriptEvaluator" and "ClassBodyEvaluator" into a common
base class "EvaluatorBase".
The generated class files and the
used to load classes defined outside the current compilation unit are now stored in thread-local globals. The
IClassLoader also holds the formerly global
IClass cache, which caused a memory leak (reported by
Fabrice Carnet 2003-05-20).
did not handle primitive types (reported by Fabrice Carnet 2003-05-20).
Multiple expressions, scripts and class bodies can now be loaded into the same
that is a
ByteArrayClassLoader. This is
necessary if the expressions, scripts and classes need to refer to each other. (Requested by Fabirce Carnet
A "for" statement with an empty condition (e.g. "for(;;)") caused a
net.janino.ClassLoaderIClassLoader.ReflectionIClass holds a map that guarantees that
one-to-one. This posed a memory leak. (Reported by Fabrice Carnet 2003-05-20.)
- Documented the
Version 0.3.10, April 22, 2003
- Fixed up invocation of interface methods (reported by Reimond Bernstein 2003-04-14).
- Added references to types in same package, but different compilation unit.
- Fixed up C-style array variable declaration ("int a = ...") (reported by Reimond Bernstein 2003-04-14).
Version 0.3.9, April 02, 2003
Added the "ClassBodyEvaluator" and the "ClassBodyDemo" class. These allow you to compile a "class body", i.e. a
series of methods, variable declarations etc. (requested by Fabrice Carnet 2003-03-18).
Fixed up "IClass.getArrayType()" which only worked for loaded classes, but not for classes in the current
java.lang.ClassLoader used to load the just-compiled class now uses as its parent the current
thread's context class loader (reported by Fabrice Carnet 2003-03-26).
Version 0.3.8, March 05, 2003
- Fixed a bug in the flow analysis code (caused a compile-time error) (reported by Fu Li Chen 2003-02-21).
"IClass" now uses "Thread.currentThread().getContextClassLoader().loadClass()" instead of "Class.forName()"
(feature requested by Dain Sundtrom 2002-02-16).
Version 0.3.7, November 26, 2002
Added "this" (reference to current instance). Added primitive class literals (e.g. "int.class"). Fixed several
showstopper bugs. Added limited support for member classes.
Version 0.3.6, November 22, 2002
Added reference comparison. Added ScriptEvaluator constructors that read from InputStream, Reader or Scanner.
Version 0.3.5, November 14, 2002
Only the last import-on-demand directive in a compilation unit did work; using a class imported by an
import-on-demand directive other than the last one caused a compilation error. (Reported by Audrius Meskauskas
Version 0.3.4, November 9, 2002
- Updated the overview page.
Version 0.3.3, October 26, 2002
Renamed "ExpressionTest" and "ScriptTest" to "...Demo". Fixed up several JAVADOC bugs. "ExpressionEvaluator"
now has a "thrownExceptions" parameter. Added support for "void" type expressions to "ExpressionEvaluator".
Added JAVADOC comments. Clean up. Fixed a bug in "AmbiguousName.reclassify()".
Version 0.3.2, October 21, 2002
- Fixed a few more bugs reported by Jimmy.
Version 0.3.1, October 13, 2002
Fixed an ArrayStoreException in ScriptEvaluator that was reported by Russell White 2002-06-25.
Added reclassification of fully qualified type names: E.g. cast operation "(HashMap) xyz" did work, but
"(java.util.HashMap) xyz" didn't. Reported by Jimmy 2002-10-13.
Version 0.3, May 25, 2002
Added most missing language elements that I planned to add. The JLS is now almost completely implemented,
except for nested classes and interfaces.
This is the first version of JANINO that I will "advertise". Let's see if anybody wants to use the tool...
After all it's a 80 percent complete JavaTM compiler in only 11000+ (well-documented) lines of
Version 0.2, April 28, 2002
- Almost a rewrite. Added several painfully missing language elements.
- Added more JAVADOC.
Version 0.1.1, November 09, 2001
- Added missing sample source files to the runtime package.
- Added lots of JAVADOC comments.
