Hi,
I'm experiencing the following exception:
Code:
java.lang.NullPointerException

This tends to happen shortly after application startup under moderate/high load. Further Instantiation of the com.Customer class fail with the same exception so the application
is effectively broken until we restart.
I've traced through the code and can't see how the DefaultMethodHandler would ever be invoked in theCustomer_$$_javassist_1 since it's set in the JavassistLazyInitializer.
This is on Hibernate 3.6.8-Final with javassist 3.16.1
Has anyone seen this before? Is there any workaround possible?
Thanks
