ILW: Impact: high -> crash Likelihood: medium -> needs UseLargePages, large pages activated in the OS Workaround: medium -> disable either UseG1GC, UseLargePages or deactivate large pages in the OS -> P2

The problem is the use of large/huge pages and -XX:+UseLargePages: in that case the heap is precommitted, but some internal data structure still thinks it can commit/uncommit the heap regions.
