added ability to get remote disk sizes
Throw IOException if negative int from port-based cli connection stream.

-Instead of failing at initializing array with negative size.
Introducing PowerMock test for the zero-size array case.
Negative-size case not tested thx to unhelping PowerMock behavior.
Using ConnectionMockTest instead of ConnectionTest; needed by PowerMock.

Do not throw Error for a recoverable condition.
In this case, someone tried to add an element to a persisted list, and it was added in memory but the configuration could not be saved.
Unclear whether that should even be treated as an error condition (the write failure might be transient, and a subsequent write would store the addition),
but if it should be then we should throw a simple runtime exception.
Better null safety.
Defense against an exception consistently thrown when running functional tests against 1.532.1 (but not 1.540, for whatever reason):
