Creating JbpmConfiguration with a different jbpm.cfg.xml in an action handler causes StackOverflowError
-------------------------------------------------------------------------------------------------------
Key: JBPM-2908
URL: https://jira.jboss.org/browse/JBPM-2908
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
Caused by: java.lang.StackOverflowError

How to reproduce:
- Start SOA-P 4.3 CP04
- download and unzip reproducer.zip
- copy jbpm.1.cfg.xml and jbpm.2.cfg.xml to <SOA_HOME>/jbossas/server/<config>/deploy/jbpm.esb
- cd ProcessDefinitions
- modify build.properties
- ant deploypar
- cd ..
- cd ProcessCallWS
- modify build.properties
- ant deploy
- ant run
# jbpm.1.cfg.xml and jbpm.2.cfg.xml have same contents as this is a test reproducer
Analysis:
As the context classloader is ProcessClassLoader in action handler execution, JbpmContext.getGraphSession() -> org.hibernate.cfg.Configuration.configure() let ProcessClassLoader find resources, but ProcessClassLoader invokes JbpmContext.getGraphSession() recursively.
Once DbPersistenceServiceFactory builds SessionFactory, the loop won't happen.

If the DateToStringConverter will revert more than one Date in diffrent threads in the same time. Runtime excetion (NumberFormat....) will be thrown.
The SimpleDateFormat is not thread save!
