[jboss-jira] [JBoss JIRA] Created: (EJBTHREE-659) SFSB throws exception with second passivation
SFSB throws exception with second passivation
---------------------------------------------
Key: EJBTHREE-659
URL: http://jira.jboss.com/jira/browse/EJBTHREE-659
Project: EJB 3.0
Issue Type: Bug
Affects Versions: EJB 3.0 RC8 - FD
Reporter: Ben Wang
Assigned To: Ben Wang
Fix For: EJB 3.0 RC9 - FD
I have created a test case to illustrate this for both SimpleStatefulCache and
StatefulTreeCache, NestedBeanUnitTestCase (cache and clusteredsession). Basically, if we
do this:
bean.getXXX
sleep(10000); // to passivate
bean.getXXX; // to acitvate
sleep(10000); // to passivate again
This will produce:

This is caused by a bug from ProxiedStatefuleBeanContext serialization where we dont
serialiaze parentRef if it is not null.
