    • linux

        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

        [0.015s][error][cds] Unable to map CDS archive -- os::vm_allocation_granularity() expected: 4096 actual: 65536
