The failures reported in ~~JDK-8342849~~ and ~~JDK-8340728~~ are at bottom due to temporary direct buffers being allocated before the respective tests are actually run. This unpredictability makes the fix for ~~JDK-8340728~~ ugly and that for ~~JDK-8342849~~ difficult if not impossible. Not counting the memory used by internal temporary direct buffers toward the direct buffer memory upper limit would remove this uncertainty.
