You really are having the worst luck.  I get about 1 bug every couple
of years that turns out to be a fix I need to pickup from JDT - but
you've hit a couple!

We change the JDT compiler quite radically to implement intertype
declarations so there is always a little time of instability after
rebasing AspectJ on a new level of JDT.  I guess I prefer to suffer
that instability as infrequently as I can.  Java 7 changes in JDT will
necessitate me upgrading - but I'm not yet sure how much of that will
be coming in Eclipse 3.6.  I can imagine a rebase on Eclipse 3.6, and
tackling integration of groovy compilation at the same time.

If you hit an issue I couldn't easily pick up as a fix from JDT,
something more serious, that could cause me to do the full upgrade.
So, rest assured, you wouldn't be left hanging with a serious issue
that wasn't getting any attention.  If a full upgrade is required, it
will get done.

I like to think we prioritize important problems and get the fixes out
fast.  Did I release an AJDT with those fixes in yet?  Not sure I did,
I'll do that this week as I've a few other fixes to get out there.
