> Konstantin Kolinko reported some issues with caching that blocked the release:
> bq. I noted new methods that introduced caching into classfile.ConstantUtf8
> class. BCEL_DONT_CACHE should at least have static setter, or a static setter
> for a cache instance / a factory class. RELEASE-NOTES.txt describes this
> change as [BCEL-163] Incorporate patch file from Findbugs which does not say
> much about this change. Actually this change introduced caching for
> ConstantUtf8 and ObjectType instances.
> Emmanuel Bourg did some investigation and testing and reported back:
> bq. If nobody object I'll remove this cache, the impact on the performance is
> too important to enable it by default, and the static state smells like a
> quick and dirty implementation. This feature could return as a pluggable
> cache if someone wants to provide a patch.
> garydgregory suggested adding a flush method to clear the cache in ObjectType
