        Description

        If you build JDK on a machime with 4k pages, and then move it to machine with 64k pages, java will not start (see below).

        The problem goes away if you rebuild CDS archive.

        *This bug has signisficant impact to development process.*

        Running a simple java -version results:

        ./jdk/bin/java -version
