What does the "Failure to marshal argument(s)" org.jboss.cache.CacheException mean?

Question

I get the following exception:

org.jboss.cache.CacheException: java.lang.RuntimeException: Failure to marshal argument(s)

We use distributed JBoss cache for our web application (on Tomcat)

I have a strong feeling this is due to bad configuration, but not sure.

Edit (Correction): We use version 3.0.0.GA of Jboss cache (core)

Answer 1

This was caused by a "swallowed" exception (NotSerializableException) that was caught and not logged nor re-thrown by our code, the JBoss exception is general and not necessarily related
