2012 Jun 22 21:37:47:136 GMT +2 BW.SRC Warn [com.arjuna.ats.jta.logging.loggerI18N] BW-EXT-LOG-200000 [com.arjuna.ats.internal.jta.resources.arjunacore.savestate] [com.arjuna.ats.internal.jta.resources.arjunacore.savestate] Could not serialize a Serializable XAResource!

2012 juin 22 21:37:47:136 CEST   [com.arjuna.ats.internal.jta.resources.arjunacore.savestate] [com.arjuna.ats.internal.jta.resources.arjunacore.savestate] Could not serialize a Serializable XAResource!

This behavior was not observed with the previous version of the Transaction Manager (1.0.2).

Environment:
==========
TIBCO ActiveMatrix BusinessWorks

Symptoms:
==========
"Could not serialize a Serializable XAResource!" is reported.

Cause:
=====
This warning means TM is not able to serialize an XAResource to write to disk. The serialization is done to make recovery easier in case of XAResource, but it is not a requirement. This is a defect of TM (https://issues.jboss.org/browse/JBTM-377). However, this should not affect recovery as the TM could still get recovery information from the application that created the XAResource. Having the XAResource written to disk will make TM's job easier which is the reason this is just a warning rather than an error.

Resolution:
=======
There is no loss in functionality. This can be ignored.

Unable to serialize a Serializable XAResource.
