Hi,

Sorry for the delay with the reply. MAP_JIT actually requires few changes like this one in advance. Luckily, not all prerequisites of https://bugs.openjdk.java.net/browse/JDK-8256155 are required, as it was integrated later. Few things regarding this patch are unclear for me, we'll sync with Vladimir when he'll be back from vacation.
