Robert Becker updated JBSEAM-5123:
----------------------------------
Description:
I get infrequent ConcurrentModificationException in the SynchronizationRegistry
when starting business processes. The processes are started programmatically via
{code}
Contexts.getBusinessProcessContext().set("someVariable", myVariable);
BusinessProcess.instance().createProcess("process-name");
{code}
The exception occurs roughly about 1 in 100 times a process is started and I
was not yet able to reproduce it.
This is the full exception:
