Description (last modified by jmoore)
It's annoying that hot redeployment causes the server to choke with OOMs after one or two redeploys. Need to examine.

- Use jrockit http://dev2dev.bea.com/jrockit/
- Find held on to objects
- Due to Hibernate > 3.0.5 ?

- Switch to cglib (i.e. javassist is holding on to objects) same suggestion from spring forum)
- System.setProperty( Environment.BYTECODE_PROVIDER, "cglib" );
