I am trying to use NONSTRICT_READ_WRITE,  below statement and deployed the jars to JBoss 5.1.0 on RHEL5.

@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE, region = "sp_persistence")

When I start JBOss, following exception is throwing..

Caused by: org.hibernate.cache.CacheException: unsupported access type [nonstrict-read-write]

========

Any suggestions on this ?  Thank you.... Rao

Complete Exception details...
