CacheException when using Hibernate with JBoss Cache's optimistic locking
-------------------------------------------------------------------------
Key: HHH-2486
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2486
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.2
Environment: Hibernate 3.2.2.
JBoss Cache 1.4.1.SP2
Affects all database platforms
Reporter: Rob Worsnop

org.hibernate.action.BulkOperationCleanupAction evicts entities and then evicts entity
collections.
So, with the attached test case, it does the following (in pseudo-code):
remove /com/medq/test/A
remove /com/medq/test/A/bs // throws exception
Obviously removing "/com/medq/test/A" also removes
"/com/medq/test/A/bs", so the last line is superfluous (as well as causing an
exception to be thrown).
Is there a reason why org.hibernate.cache.OptimisticTreeCache.clear doesn't call
option.setFailSilently(true)? The exception would be swallowed by JBoss Cache if it did.
Here's the stack trace:

As a workaround, the region name for the entity collection can be overridden so that it
isn't underneath the entity in the tree.
In other words, something like "collections/com/medq/test/A/bs" instead of the
default "com/medq/test/A/bs"
