[jboss-dev-forums] [Design of POJO Server] - Re: FIELD granularity web session replication tests

[bstansberry@jboss.com]

Problem seems to arise from the FieldBasedSessionPassivationTestCase.testRedeploy() test, which deploys a war, undeploys it and deploys it again.  Trying to store a Person object in PojoCache fails after the redeploy:

Trying to track down what's happening here in a debugger, I see that the Person class being manipulated is the old class from before the redeploy.
