Summary:
    When running in CDS mode, the following 2 tests fail:
    compiler/profiling/spectrapredefineclass/Launcher.java
    compiler/profiling/spectrapredefineclass_classloaders/Launcher.java

Platform:
    Found on Linux-x64 bit platform

Reproducible: 100%
    Occasionally the sharing may fail due to archive file mapping failure.
    This happens very occasionally on Linux, more often on Windows.

Version:
    Java(TM) SE Runtime Environment (fastdebug build 9-internal+0-2016-03-21-132215.mikhailo.hs-rt)
    Java HotSpot(TM) 64-Bit Server VM (fastdebug build 9-internal+0-2016-03-21-132215.mikhailo.hs-rt, mixed mode, sharing)
    hs-rt as of 3/21/2016
   
Steps to reproduce:
    java -Xshare:dump // this will create a shared archive
    java -Xshare:auto -version // check, ensure the keyword 'sharing' appears in the version

    Run test: jtreg -Xshare:auto hs-rt/hotspot/test/compiler/profiling/spectrapredefineclass/Launcher.java
    Note that if you run w/o -Xshare:auto, the test works well
