IType.resolveType very slow in 3.4 [message #257017]

I just upgraded from 3.2.1 to 3.4 and found that my plug-in became very
slow. I do a lot of java introspection using IType. I found that the
biggest performance degradation was caused by calling resolveType(String).
It is several times slower than 3.2.1. I have plenty of heap memory left
so it is not that. Why is resolveType so slow in 3.4 or am I the only one
that is seeing this?

Thanks,

Steve

I haven't heard any other reports of a slowdown; the JDT performance tests
don't show one, or 3.4 wouldn't have been released.

Are you able to reproduce this in a test case that you could post in a
Bugzilla bug?
