- Fixed missing retention of method annotations of instrumented types.
- Allowed dynamic lookup of methods for the

SuperMethodCallinstrumentation to fall back to a default method call if required. A different behavior was found to surprise users and would introduce subtle bugs in user code as the super method instrumentation would always work with subclassing due to Java super method call semantics. - Added a
MethodCallinstrumentation that allows hard-coding a method call. - Added an
InvokeDynamicinstrumentation that allows runtime dispatching by bootstrap methods. - Fixed the default
TypePoolto retain generic signatures in order to avoid that agents delete such signatures. - Fixed a bug in all of the the default

mainly for allowing the reuse of
Methodinstances for the@Originannotation and theInvocationHandlerAdapter.
- Changed the semantics of the

- Refactored the invocation of super methods to be created by an
Instrumentation.Target. For a future release, this hopefully allows for class redefinitions using today's API for creating subclasses. - Upgraded to ASM 5.0.3.
- First general release.
