I get the following exception when trying to update a Local TX Datasource via the Profile Service: anonymous wrote : Failed to update Resource (see app server log for additional details):

AOPProxy$1.updateComponent(AOPProxy$1.java) at org.rhq.plugins.jbossas5.JndiResourceComponent.updateResourceConfiguration(JndiResourceComponent.java:139) Based on some debugging, it looks like the Object it's trying to serialize when the NotSerializableException is thrown is a Proxy to a following CompositeValueSupport object whose toString() looks like: CompositeValueSupport: metaType=[MutableCompositeMetaType{org.jboss.metatype.api.values.CompositeValue items=[name=name type=java.lang.String], [name=type type=java.lang.String], [name=value type=java.lang.String]}] items=[name=SimpleMetaType:java.lang.String:UserName,type=SimpleMetaType:java.lang.String:java.lang.String,value=SimpleMetaType:java.lang.String:sa] When it hits the h field of the Proxy, which is of type CompositeValueInvocationHandler, the exception is thrown. Does anyone know what could be causing this? Please let me know if there's something I can do to get past it. If it's a bug, I'll be glad to create a JIRA for it.
