      The JCA code did not properly handle multi-threaded access, due to several potential causes of deadlocks involving JDBC operations and the JBossTS transaction reaper thread. The JCA code has been updated to resolve these problems, and multi-threaded access should work properly in the JCA.

      The attached dumps contain 4 dead-locks involving JCA (i.e. JDBC operations) and the JBossTS transaction reaper thread. It appears that the JCA code is not properly handling multi-threaded access properly resulting in a dead-lock.
