Why is TransactionManagerLookup ignored when using batch mode?

[jeremystone]

We are using the Tree Cache API (and therefore must have invocation batching enabled) for some parts of our application.

After upgrade from 5.1.6 to 5.2.0, even though we have a TransactionManagerLookup configured, the resulting JTA transaction manager is not being used for the cache. Instead (see org.infinispan.factories.TransactionManagerFactory) a BatchModeTransactionManager is used.

The result is that we get something like the following when we try to access the cache (despite there being an active JTA transaction):

java.lang.IllegalStateException: This is a tx cache!

Your wiki entry https://community.jboss.org/wiki/BatchModeTransactionManager implies use of JTA with batch mode should be perfectly ok.

It is interesting to note that tests that use a DummyTransactionManager will (by virtue of it sharing the same static thread local for the current Transaction with the BatchModeTransactionManager) not see this issue.

I can provide test case if reqd.

Thanks for reporting this Jeremy. Can you please create a JIRA[1] and upload the test for it?
