> A {{RemoteCacheManager}} instance is created for each test method in {{RemoteQueryDslConditionsTest}}, because of the {{@CleanupAfterMethod}} annotation. But the {{@AfterTest}} method that stops the remote cache is only once for the entire class, so all but one of the remote cache managers are not stopped properly.
> {{GenericKeyedObjectPool}} registers a timer in {{EvictionTimer}}, which keeps the pool and the {{TcpTransport}} objects in it alive. And because the size of the buffer used by the transport is very big (1838kb on my system), {{RemoteQueryDslConditionsTest}} and its subclasses can quickly fill up the heap.
