G1: Heap expansion logging misleading for fully expanded heap

XMLWordPrintable

        When running G1 with -XX:+PrintAdaptiveSizePolicy some information about the heap sizing is logged. When the heap is fully expanded but the ergonomics would have liked to expand even more the following message is logged:

        [G1Ergonomics (Heap Sizing) did not expand the heap, reason: heap expansion operation failed]

        It sounds like something failed, but in reality we just hit the -Xmx value. We should have a more informative message that does not look like a serious failure.
