Hi,

In my application, I'd like to be able to delete open (pending) process instances. My process instances usually consists of 2-8 subprocesses. The delete of the parent should be able to cascade delete its forked executions and its sub-processes, their forked children and their subprocesses. I'm running into

org.hibernate.exception.ConstraintViolationException: could not delete: [org.jbpm.pvm.internal.model.ExecutionImpl#23]
    at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:94)
    at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66)
    at org.hibernate.persister.entity.AbstractEntityPersister.delete(AbstractEntityPersister.java:2559)

when doing a cascade delete. Seems that the process attempts to delete the parent record immediately, without looking for children processes.

Below is the complete unit test to reproduce the issue:

Your input would be highly appreciated.
