Hi everyone,

I am using Hibernate version 2.1.2 and I am running into OutOfMemoryError exception with cglib. I want to find out if anyone can share some light with this problem. Here is the exception that I get:

net.sf.hibernate.InstantiationException: Could not instantiate entity with CGLIB: qatest.qaav4.Customer

Caused by: java.lang.OutOfMemoryError

Can someone give some suggestions on how to fix this problem?? Thanks

Try to dissable cglib reflection optimizations, but I think you will get this error without cglib too. Probably you have less memory than query result.
