RELEASE NOTES


Introduction
------------
The Apache Commons BCEL team is pleased to announce the release of
Apache Commons BCEL 6.6.0!

The Byte Code Engineering Library (BCEL) is intended to give users a convenient

Apache Commons BCEL
    Version 6.1
  RELEASE NOTES


Introduction

The Apache Commons BCEL team is pleased to announce the release of
Apache Commons BCEL 6.1!

The Byte Code Engineering Library (BCEL) is intended to give users a convenient
way to analyze, create, and manipulate compiled .class files. Classes are
represented by objects containing all the symbolic information of the given
class: methods, fields and byte code instructions.

Apache Commons BCEL 6.1 is a bugfix and feature release supporting bringing
experimental support for Java 9.

It requires Java 7 or higher to run.


COMPATIBILITY with 6.1
----------------------

Binary compatible - Yes

Source compatible - Yes, sort of;
 - The org.apache.bcel.classfile.Visitor interface has been enhanced with
 additional methods. If you implemented it directly instead of extending
 the EmptyVisitor class you'll have to implement the new methods.
 - The org.apache.bcel.generic.Visitor interface has been enhanced with an
 additional method. If you implemented it directly instead of extending
 the EmptyVisitor class you'll have to implement the new methods.

Semantic compatible - Yes

For full information about API changes please see the extended Clirr report:


https://commons.apache.org/bcel/clirr-report.html


COMPATIBILITY with Java 9
-------------------------

The MANIFEST.MF now contains an additional entry:

  Automatic-Module-Name: org.apache.bcel

This should make it possible to use Commons BCEL 6.1 as a module in the Java 9
module system. For more information see the corresponding issue and the
referenced mailing list discussions:

https://issues.apache.org/jira/browse/BCEL-293

The build currently on Java 9 fails with test failures related to Locales. We
are still working on this. For more information see:

https://issues.apache.org/jira/browse/BCEL-275


New Features
-------------

* BCEL-293: Add Automatic-Module-Name MANIFEST entry for Java 9 compatibility.
* BCEL-292: Add minimal Java 9 support.

Fixed Bugs
-----------

* BCEL-286: Utility.signatureToString fails if a method has multiple type
            arguments. Thanks to Mark Roberts.
* BCEL-287: IINC does not handle -128 properly. Thanks to Mark Roberts.
* BCEL-283: Support for StackMap should be different from StackMapTable.
            Thanks to Mark Roberts.
* BCEL-289: Crash when parsing constructor of inner classes with parameters
            annotated.
* BCEL-276: LocalVariableTypeTable is not updated.
            Thanks to Sam Yoon, Mark Roberts.
* BCEL-277: Resolving the String representation of a constant throws
            NoSuchElementException in case of CONSTANT_NameAndType constant.
            Thanks to Sam Yoon.


Have fun!

Release Notes for 6.0


Introduction
------------
The Apache Commons BCEL team is pleased to announce the release of
Apache Commons BCEL 6.0!

The Byte Code Engineering Library (BCEL) is intended to give users a convenient
way to analyze, create, and manipulate compiled .class files. Classes are
represented by objects containing all the symbolic information of the given
class: methods, fields and byte code instructions.

Apache Commons BCEL 6.0 is a major release supporting the new features
introduced in Java 6, 7 and 8.

It requires Java 7 or higher to run.


COMPATIBILITY with 5.2
----------------------

Binary compatible - not strictly compatible
- The constant interface org.apache.bcel.Constants has been deprecated. Classes
 which implemented this interface in 5.2 now use the constants defined in the
 org.apache.bcel.Const class.
- The constant interface org.apache.bcel.generic.InstructionConstants has been
 deprecated. Classes which implemented this interface in 5.2 now use the
 constants defined in the org.apache.bcel.generic.InstructionConsts class.
- Return type of method 'public java.lang.Object getElementAt(int)' in
 org.apache.bcel.verifier.VerifierFactoryListModel has been changed to
 java.lang.String.
- The BCEL classes do no longer implement java.io.Serializable.

Source compatible - Yes, sort of;
 - The org.apache.bcel.classfile.Visitor interface has been enhanced with
 additional methods. If you implemented it directly instead of extending
 the EmptyVisitor class you'll have to implement the new methods.
 - The org.apache.bcel.generic.Visitor interface has been enhanced with an
 additional method. If you implemented it directly instead of extending
 the EmptyVisitor class you'll have to implement the new methods.

Semantic compatible - Yes, except:
 - BCEL 6.0 handles new attributes such as code annotations that could only
 be processed by implementing a custom AttributeReader in the previous
 versions. Code relying on this behavior will have to be adjusted since
 the AttributeReader will no longer be called in these cases.

For full information about API changes please see the extended Clirr report:


https://commons.apache.org/bcel/clirr-report.html

New Features
-------------

* BCEL-272: Add constants for Java 9 class file version 53.

Fixed Bugs
-----------

* BCEL-237: non-empty final arrays should be private as they are mutable.
* BCEL-243: Type.getType() needs to understand TypeVariableSignature(s).
* BCEL-271: FCONST pattern does not include FCONST_2.
* BCEL-264: Add missing Node.accept() implementations (ConstantMethodHandle,
            ConstantMethodType, ParameterAnnotationEntry).
* BCEL-221: BCELifier is not working for Java8Example (incomplete).
* BCEL-195: Addition of hashCode() to generic/Instruction.java breaks Targeters.
            Never make distinct BranchInstructions compare equal.
* BCEL-261: Select constructor allows partially constructed instance to escape.
