> Problem is JBossEntityMetaData.getCacheInvalidationConfig() can return null if jobss.xml doesn't include a cache-invalidation-config element; in 4.x it wouldn't because a default value would be set.
> Likely solution is either 1) to add a JBossEntityMetaData.determineCacheInvalidationConfig() method or 2) just lazy create a default config in JBossEntityMetaData.getCacheInvalidationConfig().  The latter is a simpler solution; the former is used elsewhere when there is a need to merge metadata from a <container-configuration/>, but there is no cache invalidation configuration in <container-configuration/>.
> Either way, this will require a new jboss-metadata release.
