Apache Commons BCEL 6.0 RELEASE NOTES
The Apache Commons BCEL team is pleased to announce the commons-bcel6-6.0 release!
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.
BCEL 6.0 is a major release supporting the new features introduced in Java 6, 7
and 8. It requires Java 5 or higher to run.
Compatibility with 5.2
----------------------
Binary compatible - No
Source compatible - Yes, sort of;
- Maven coordinates update:
org.apache.bcel:bcel:5.2 -> org.apache.commons:commons-bcel6:6.0
- Rename package imports:
org.apache.bcel -> org.apache.commons.bcel6
- The org.apache.commons.bcel6.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.
Semantic compatible - Yes, except:
- BCEL 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.
-------------------------------------------------------------------------------
Changes in this version include:
Fixed Bugs:
o Bug fixes and improvements to InvokeDynamic and BootStrapMethods implementation.
Issue: BCEL-209. Thanks to Mark Roberts.
o Verification error when an invoke references a method defined in superclass.
Issue: BCEL-187. Thanks to Jérôme Leroux.

o The verifier now checks if methods with a void return type attempt to return an
object. Issue: BCEL-184. Thanks to Jérôme Leroux.
o The verifier now checks if methods with a void return type attempt to return an
object. Issue: BCEL-184. Thanks to Jérôme Leroux.
o MethodGen.removeLocalVariable now properly unreference the removed variable
from the targetters of the instruction handlers delimiting the scope of
the variable. Issue: BCEL-207. Thanks to Mark Roberts.

found in generic signatures. Issue: BCEL-197. Thanks to Mark Roberts.
o Removed the 'index' variable from the LocalVariableGen's hash code.
