      Description

      If virtual memory has been limited with "ulimit -v", and the server has a lot of RAM, then the JVM can not start without extra command line arguments to the GC.

      Both XX:MaxHeapSize and XX:CompressedClassSpaceSize have to be specified. (there may be other combinations that work, I have not tried all)
      It would be good if the jvm could start without extra command line args, even if virtual memory has been limited.
      There is an old bug for this that was resolved in jdk8, but it is still failing in jdk9.


      This log is from a server with 32G ram:
