ConcurrentMapManager NullPointerException

[psfung]

I found the following error logs after upgrading from Hazelcast 1.9.4.8 to 2.0.2. No exception is thrown to my application, so I don't know which API call cause these problems.

This is fixed both in master and in 2.0 branch. But it is harmless, you can ignore until we release the new version.
