Hi Andrew,

Yes, that worked. Many thanks for your help.

All the best,

It looks like you have a problem in your configuration that is
preventing your bundles' dependencies graph from being read from the
cache.  This could happen if you had an error while shutting down.  In
most cases, this problem doesn't mean much (except for a slightly
longer startup time), but in this case, the exception is preventing
the org.eclipse.equinox.weaving.aspectj bundle from being autostarted
(and hence no jdt weaving).

I would recommend restarting once with the -clean option.  Make sure
that this exception does not occur.  Then restart again without -clean
(and ensure no exception).  Finally, try restarting the weaving
service.  This may fix your problem.

I'd also recommend reverting to your original config.ini as the
changes that you made should not affect things one way or the other.

Let me know if this helps.

Backporting would be a large effort as AJDT and AspectJ are moving
forward quite rapidly now we have a larger team.  If there was enough
feedback that this made an amazing difference on 3.5/3.6, we might
think about the backport.

cheers
