Not sure why ecj compilation fails with this, but not in the original PR. |

@ezzarghili Any update on this? Thanks! |

@zakkak Could you please fix the checkstyle issue? |
First, we use a separate accessor for page-alignedness as it doesn't need the more sophisticated initialization of the directMemory field. Next, ensure PhysicalMemory initialization is serialized and when it is, set directMemory to a static value so that the container code can finish initialization without introducing a cyle. The final directMemory value based on the heap size is then published to JDK code by setting the VM init level to 1. Therefore, application code would use the non-static value as the upper bound. Closes: oracle#556 (cherry picked from commit 1ae2dc0)
