NullPointerException in BatchingInterceptor when using nontransactional cache
-----------------------------------------------------------------------------

                 Key: ISPN-1503
                 URL: https://issues.jboss.org/browse/ISPN-1503
             Project: Infinispan
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 5.1.0.BETA3
            Reporter: Aaron Douglas
            Assignee: Mircea Markus


When setting a cache to non-transactional with the following configuration statement:
{code:xml}
<transaction transactionMode="NON_TRANSACTIONAL" />
{code}

I'm getting a NullPointerException in org.infinispan.interceptors.BatchingInterceptor.handleDefault(InvocationContext, VisitableCommand) because there is no transaction manager defined.  This is occurring in the fifth line below:
{code}
   protected Object handleDefault(InvocationContext ctx, VisitableCommand command) throws Throwable {
      Transaction tx;
      if (!ctx.isOriginLocal()) return invokeNextInterceptor(ctx, command);
      // if in a batch, attach tx
      if (transactionManager.getTransaction() == null && (tx = batchContainer.getBatchTransaction()) != null) {
         try {
            transactionManager.resume(tx);
            //If there's no ongoing tx then BatchingInterceptor creates one and then invokes next interceptor,
            // so that all interceptors in the stack will be executed in a transactional context.
            // This is where a new context (TxInvocationContext) is created, as the existing context is not transactional: NonTxInvocationContext.
            InvocationContext txContext = icc.createInvocationContext(true);
            txContext.setFlags(ctx.getFlags());
            return invokeNextInterceptor(txContext, command);
         } finally {
            if (transactionManager.getTransaction() != null && batchContainer.isSuspendTxAfterInvocation())
               transactionManager.suspend();
         }
      } else {
         return invokeNextInterceptor(ctx, command);
      }
   }
{code}

And the stacktrace:
