[jboss-jira] [JBoss JIRA] Updated: (JASSIST-28) javassist enhancement failed on deserializing hibernate proxies

[Armin Haaf (JIRA)]

     [ http://jira.jboss.com/jira/browse/JASSIST-28?page=all ]

Armin Haaf updated JASSIST-28:
------------------------------

    Attachment: TestJavassistSerializationPerformance.java

you need hibernate 3.2.0 (and all libs used by it) and javassist 3.3

adapt the database settings

for testing, start the main method in a vm
then start the junit test "testStartClients" in another vm

I do the tests in intellij idea. You will see the mentioned exceptions. If you change the byte code provider to cglib, the test runs without problems
