AspectJ 1.6.12 Readme

The full list of resolved issues in 1.6.12 is available here.

1.6.12.M1 available 7-Jun-2011

Notable Changes

M1 - synthetic is supported in pointcut modifiers 327867

It is now possible to specify synthetic in pointcuts:

pointcut p(): execution(!synthetic * *(..));

M1 - respect protection domain when generating types during weaving 328099

This enables us to weave signed jars correctly. AspectJ sometimes generates closure classes during weaving and these must be defined with the same protection domain as the jar that gave rise to them. In 1.6.12.M1 this should now work correctly.

M1 - Suppressions inline with the JDT compiler 335810

Starting with Eclipse 3.6, the Eclipse compiler no longer suppresses raw type warnings with @SuppressWarnings("unchecked"). You need to use @SuppressWarnings("rawtypes") for that. AspectJ has now been updated with this rule too.

M1 - Optimized annotation value binding for ints 347684

The optimized annotation value binding now supports ints - this is for use when you want to match upon the existence of an annotation but you don't need the annotation, you just need a value from it. This code snippet shows an example:

@interface SomeAnnotation {
  int i();
}

before(int i): execution(* *(..)) && @annotation(SomeAnnotation(i)) {

Binding values in this way will result in code that runs *much* faster than using pointcuts that bind the annotation itself then pull out the value.

Under that same bug some changes were made to match values by name when binding too. Suppose the annotation had multiple int values, how would we select which int to bind? AspectJ will now use the name (if it can) to select the right value:

@interface SomeAnnotation {
  int mods();
  int flags();
}

before(int flags): execution(* *(..)) && @annotation(SomeAnnotation(flags)) {

Here the use of 'flags' as the name of the value being bound will ensure the 'flags' value from any SomeAnnotation is bound and not the 'mods' value.
