            Bug ID: 205523
           Summary: java/openjdk8: support getThreadCpuTime()
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: Individual Port(s)
          Assignee: java at FreeBSD.org
          Reporter: duraid at octopus.com.au

             Flags: maintainer-feedback?(java at FreeBSD.org)

For some years now, FreeBSD java users have encountered:

java.lang.UnsupportedOperationException: Thread CPU time measurement is not
supported.
    at sun.management.ThreadImpl.verifyThreadCpuTime(ThreadImpl.java:232)
    at sun.management.ThreadImpl.getThreadCpuTime(ThreadImpl.java:251)
    at sun.management.ThreadImpl.getThreadCpuTime(ThreadImpl.java:222)

which is particularly problematic when dealing with (buggy) software that
assumes getThreadCpuTime() calls will succeed.

Will Andrews has apparently fixed this issue, see:

http://mail.openjdk.java.net/pipermail/bsd-port-dev/2015-May/002557.html

for a description and patches. It would be great to have this issue fixed in
the JDKs distributed with FreeBSD.
