[castor-dev] Patch for XMLClassDescriptorResolverImpl to fix non-thread-safe issue #CASTOR-2019

[Torsten Juergeleit]

Hi,

attached to http://jira.codehaus.org/browse/CASTOR-2019 #CASTOR-2019 you
can find a unit test which shows (on a reasonable sized multi-core system)
that the current implementation of
XMLClassDescriptorResolverImpl$DescriptorCacheImpl isn't thread-safe.

Another patch attached to #CASTOR-2019 introduces thread-safetyness to
XMLClassDescriptorResolverImpl by synchronizing accesses to
XMLClassDescriptorResolverImpl$DescriptorCacheImpl with a
ReentrantReadWriteLock. To workaround the descriptor iterator issue the
iterator is created on a copied list of the cached descriptors.

Cheers,
Torsten

Thanks, Torsten. We will give feedback through the Jira issue.
