[infinispan-dev] failing queries on one node

[Ales Justin]

Also to add ...

With some more testing, it showed that it is *slave* node's queries that failed.

I setup a static master node selection: via jgroupsMaster / jgroupsSlave.
When I changed the node type, different test failed.

e.g. if node A was slave, queryOnA, indexGenAndQueryInsertOnA, testContentOnA failed.
if node B was slave, simply change A --> B in test names above

This is the full test:

As Sanne mentioned, that locking issue on Lucene cache's looks suspicious ...
