Description William Ono CLA 2005-05-31 19:09:14 EDT 
This is not bug #96111 - the stack trace is different.  (To work around that
one, I have changed all private fields referenced by privileged aspects to public.)

Unfortunately I don't have a reasonably sized block of code to show the problem
- sorry - I'll try to cook one up soon.

public class FooClass {
	java.util.Vector<Object> v;
}

public aspect FooAspect {
	public void FooClass.setV(java.util.Vector<Object> v) { this.v = v; }
}

Fixing generic signature parsing for M3.  This bug doesn't manifest on M2, only
on the latest dev builds.
Comment 3 Andrew Clement CLA 2005-06-01 12:20:00 EDT 
Thanks for the simple test case, I've just checked in the fix for this.  It is
to do with TypeX signature processing not coping with generic signatures.  Fix
will appear in a dev build shortly.
Comment 4 Andrew Clement CLA 2005-06-03 11:33:21 EDT 
Fixed in latest dev build from http://eclipse.org/aspectj/downloads.php
