IllegalStateException when Query Cache is enabled

I've updated AS7 sources from master branch, then enabled Query cache in SecondLevelCacheTestCase (put <property name="hibernate.cache.use_query_cache" value="true"/> in persistence.xml) and then got IllegalStateException. This tests passes but the exception can be found in server.log:

ERROR [org.infinispan.interceptors.InvocationContextInterceptor] (pool-4-thread-1) ISPN000136: Execution error: java.lang.IllegalStateException: Transaction TransactionImple < ac, BasicAction: 0:ffff7f000001:cbbd222:4f1f2b9a:8 status: ActionStatus.COMMITTED > is not in a valid state to be invoking cache operations on.

server output: http://pastebin.com/xMZEuMp1

When Query cache is disabled, everything is OK.
