Creating JbpmConfiguration with a different jbpm.cfg.xml in an action handler causes
StackOverflowError

Project: jBPM
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Runtime Engine
Affects Versions: jBPM 3.2.9
Environment: SOA-P 4.3.0 CP04
Reporter: Toshiya Kobayashi
I tried to switch jbpm.cfg.xml (= create JbpmConfiguration with a different jbpm.cfg.xml)
and start a process instance in my action handler.
Client:
1. Create a JbpmConfiguration with "jbpm.1.cfg.xml"
2. Create a JbpmContext with the JbpmConfiguration(jbpm.1.cfg.xml)
3. Create and start a process instance
Action handler of the process:
4. Create JbpmConfiguration instance with "jbpm.2.cfg.xml"
5. Create a JbpmContext with the JbpmConfiguration(jbpm.2.cfg.xml)
6. jbpmContext.getGraphSession() causes infinite loop and ends up with StackOverFlowError

Attachment: JBPM-2908-testcase.patch
JBPM-2908-ProcessClassLoader-tentative.patch
I've attached a unit test and ad-hoc patch for ProcessClassLoader.
The test is only for detecting StackOverflowError. This nested JbpmContext usage may not
be properly asserted except an integration test using externally managed transaction(JTA),
I guess. This test ignores lots of JbpmPersisteceException... So it may not be a valid
test case, but is useful for understanding the issue.
The ProcessClassLoader patch is really ad-hoc fix -- just to make sure it pass the test
case... don't take it serious :)

I tried to switch jbpm.cfg.xml (= create JbpmConfiguration with a different jbpm.cfg.xml)
and start a process instance in my action handler.
Client:
1. Create a JbpmConfiguration with "jbpm.1.cfg.xml"
2. Create a JbpmContext with the JbpmConfiguration(jbpm.1.cfg.xml)
3. Create and start a process instance
Action handler of the process:
4. Create JbpmConfiguration instance with "jbpm.2.cfg.xml"
5. Create a JbpmContext with the JbpmConfiguration(jbpm.2.cfg.xml)
6. jbpmContext.getGraphSession() causes infinite loop and ends up with
StackOverFlowError

----------------------------------------
Prevented stack overflow when parsing alternate configuration resource from action handler
by keeping a reference to the JbpmConfiguration that created the ProcessClassLoader.
WARNING. May cause regression. Fix needs to be tested for acceptance.
