Hi,

I have exactly the same problem when I install fix pack 13 on WAS 5.0.2 using Hibernate 2.1.8 (actually I install it in the test environment of WSAD 5.1.0 which is a 5.0.2 server).

Tracing it, it appears that it hangs on this line in SessionFactoryImpl :

Code:

static {
QUERY_KEY_FACTORY = (QueryCacheKeyFactory) KeyFactory.create(QueryCacheKeyFactory.class);
...

which is using classes in CGLIB.

If I uninstall the fix pack, it works again.

Any idea to help me understand ?

I cannot find source code from cglib-full-2.0.2.jar to trace it further.

Thanks.

Hi,

I think I have found the explanation. There is a page from IBM mentioning that if you upgrade to fix pack 12 or above, you need also to upgrade the JDK 1.3.1 to SR8 :

http://www-1.ibm.com/support/docview.wss?rs=180&context=SSEQTP&dc=D600&uid=swg21221783&loc=en_US&cs=UTF-8&lang=en

Here is the link for the upgrade :
http://www-1.ibm.com/support/docview.wss?rs=180&uid=swg24007622

Sorry for polluting this forum with WebSphere problems but it had an impact on Hibernate and the upgrade worked for us.

Good luck !
