---------------------------------------
For future reference, he's further analysis I did on this JIRA:
- https://jira.jboss.org/browse/ISPN-666: As said in the JIRA, there're a couple of
places from where JBoss Marshalling can return NotSerializableException when marshalling:
a) Within JBoss Marshalling, an instance of org.jboss.marshalling.util.IdentityIntMap
maintains the known classes for which JBoss Marshalling can provide its own efficient
marshalling, i.e. ArrayList...etc. Now, when this map is queried and the class cannot be
found (i.e. a user or Infinispan defined object is returned), the map should return -1.
Now, if the map ended up returning anything other than -1 for the case of user/Infinispan
objects, a NotSerializableException would be thrown. This would mean that somehow that
IdentityIntMap is getting corrupted.
b) The other place from which NSE can be thrown in this case would be if
ConstantObjectTable.getObjectWriter() returned null for MultipleRpcCommand. Now, for that
to happen, MultipleRpcCommand would need to be missing from writers map in
ConstantObjectTable. Now, ReplicationQueue, which is the one throwing this error, starts
(priority = 10) after VAM (priority = 9), so can't see how writers map could be
corrupted or half empty. Maybe another case of multiple cacheManager.getCache() ending up
with some weird writers map? Can't say.
MultipleRpcCommand being serialized ignoring the @Marshaller
