Subject: [PATCH] 8055525: Bigapp weblogic+medrec fails to startup after
 JDK-8038423 Summary: If large pages are enabled and configured in Linux, the
 VM always pre-commits the entire space. The VM fails verification of the
 commit of the initial heap because some internal data structure marked all
 memory pages of the heap as committed during initialization. This makes the
 code think that we attempted a double-commit during first allocation of the
 heap. Remove the initial marking of memory pages of the heap to committed.
