Here is the info ragarding time taken by each test in my local env.

> Key: BOOKKEEPER-408
> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-408
> Project: Bookkeeper
> Issue Type: Bug
> Components: bookkeeper-server
> Affects Versions: 4.1.0
> Environment: SUSE System
> ZooKeeper server
> three BookKeepers
> Reporter: liuyang
>
> When I run the tests of BookKeeper, I found that the test running forever and
> cannot be finished. The log has the exception that is
> "junit.framework.AssertionFailedError: Return code is not OK: -6".
> I thought this issuse might be come from the synchronization mechanism used
> by the BookieReadWriteTest.
> for example in BookieReadWriteTest.TestReadWriteAsyncSingleClient()
> 1. when called the function lh.asyncAddEntry(entry.array(), this ,sync), the
> call back function is addComplete(int, LedgerHandle, long, Object)
> 2. we can see that in addComplete(..) the function will be fail when rc !=
> BKException.Code.OK, and the x.counter++ will not be called never.
> 3. we assume that the function addComplete(..) is fail. so, in
> TestReadWriteAsyncSingleClient(), the while loop enter endless loop because
> sync.counter < numEntriesToWrite is right forever.
