8014765: VM exits if MaxTenuringThreshold is set below the default InitialTenuringThreshold, and InitialTenuringThreshold is not set
Summary: The VM exits when the condition in the subject line applies. The fix sets InitialTenuringThreshold to MaxTenuringThreshold if it is larger than MaxTenuringThreshold and InitialTenuringThreshold has not been set (is default).
