Paweł Kępka commented on HHH-4317:
----------------------------------

Ondrej, on JRE5 and JRE6 calling a method by reflection works much better then 100 times slower but it takes some time JIT complier to optimize it. 
I believe that your solution should solve the issue.

> Holding enum values in static enumValues map in EnumType class causes memory leaks on application server where hibernate is loaded by application server's common classloader (like for default configuration of JBoss4).
> SoftReference or SessionFactory based caching should be used instead.
