[infinispan-issues] [JBoss JIRA] Updated: (ISPN-1020) HotRod client test suite hangs in ClientConnectionPoolingTest.tearDown

Dan Berindei updated ISPN-1020:
-------------------------------

    Fix Version/s: 4.2.2.BETA1
                   5.0.0.BETA1


I updated the pull request to fix the ClientConnectionPoolingTest test.

It turns out the problem was that RemoteCacheImpl.ping was leaking a transport and was changing the number of connections in the pool, so I added another commit that fixes the leak.

The leak was present only on the master branch, but I think it's still good to have the tests look the same everywhere so I kept the t_ispn1020_4.2.x branch with the updated tests.
