Vojtech Juranek commented on ISPN-4813:
---------------------------------------

IIRC I put [AbstractRemoteCacheIT#assertCacheEmpty|https://github.com/infinispan/infinispan/blob/master/server/integration/testsuite/src/test/java/org/infinispan/server/test/client/hotrod/AbstractRemoteCacheIT.java#L113] at the beginning of AbstractRemoteCacheIT#[testPutAsync|https://github.com/infinispan/infinispan/blob/master/server/integration/testsuite/src/test/java/org/infinispan/server/test/client/hotrod/AbstractRemoteCacheIT.java#L566] to make sure that cache is clear, but latter on, when I put a break point into [DefaultDataContainer#clear|https://github.com/infinispan/infinispan/blob/master/core/src/main/java/org/infinispan/container/DefaultDataContainer.java#L205] it wan't called. Not sure if this is the right data container, but IIRC via JMX this method was called.

> Number of cache entries ({{numberOfEntries}}) provided by JMX is wrong. {{HotRodRemoteCacheIT#testPutAsyc}} fails with assert error (see bellow), because JMX returns wrong number of entries in the cache. When debugging the test, number of entries in the cache is correct (100 - obrained e.g. by {{cache.getBulk().size()}}), but JMX return wrong number (100). Even on cleared cache JMX return that it contains 3 entries. When the {{clear}} operation is called via JMX, JMX show correct number (0).
