Description
To enable applications to control how and when to allow for more or less GC, the flags -XX:MinHeapFreeRatio and -XX:MaxHeapFreeRatio should be made manageable.
Support for these flags should also be implemented in the default parallel collector.
                                    

Comments
Release note (7u60):
The flags MinHeapFreeRatio and MaxHeapFreeRatio have been made manageable. This means they can be changed at runtime using the management API in Java. Support for these flags have also been added to the ParallelGC as part of the adaptive size policy.
