1456a4c423 6941275: G1: The MemoryPools are incorrectly supported for G1 
The way we were caluclating the max value meant that it might fluctuate during the run and this broke some assumptions inside the MBeans framework. This change sets the max value of each pool to -1, which means undefined according to the spec.
