The following PRT job to c2_baseline has broken 5 MM_REGRESSION tests:

    java/lang/management/ThreadMXBean/FindDeadlocks.java
    java/lang/management/ThreadMXBean/GetAllLockedSynchronizers.java
    java/lang/management/ThreadMXBean/Locks.java
    java/lang/management/ThreadMXBean/ThreadBlockedCount.java
    java/lang/management/ThreadMXBean/ThreadStateTest.java

Partial 6281377: provide Unsafe lazy field set methods
This putback completes VM (but not JDK) changes necessary for 6281377.
There will be coordinated changes to JDK code in a few weeks.

Reviewed by: never, kbr

Fix verified (y/n): y

Verification testing:
 - Inspected PrintOptoAssembly for the expected intrinsic code.
 - Doug Lea has run library units for the new intrinsic.

Here is my analysis log entry:

New MM_REGRESSION failures (from 2005.06.24)
* java/lang/management/ThreadMXBean/FindDeadlocks.java
* java/lang/management/ThreadMXBean/Locks.java
* java/lang/management/ThreadMXBean/ThreadBlockedCount.java
* java/lang/management/ThreadMXBean/ThreadStateTest.java
        These tests failed due to an UnsatisfiedLinkError: park and/or
        UnsatisfiedLinkError: unpark on Linux IA32, on Solaris SPARC,
        Solaris X86 and Win32 Client VMs and Linux AMD64, Linux IA32,
        Solaris AMD64, Solaris SPARC, Solaris SPARC-64, Solaris X86
        and Win-AMD64 Server VMs. These failures have also been
        observed on Win32 Server VM.

        I verified that these tests passed with the previous JDK/VM:
        JDK-B41/20050623093904.dcubed.service_hs_merge; looks like we
        picked up the failures from either JDK-B42 or:
        20050623144856.kbr.c2_to_main_baseline

        Update: See update entry below.

* java/lang/management/ThreadMXBean/GetAllLockedSynchronizers.java
        This test failed due to an IllegalMonitorStateException on
        Linux IA32, Solaris SPARC, Solaris X86 and Win32 Client VMs and
        Linux AMD64, Linux IA32, Solaris AMD64, Solaris SPARC, Solaris
        SPARC-64, Solaris X86 and Win-AMD64 Server VMs. This failure
        has also been observed on Win32 Server VM.

        I verified that these tests passed with the previous JDK/VM:
        JDK-B41/20050623093904.dcubed.service_hs_merge; looks like we
        picked up the failures from either JDK-B42 or:
        20050623144856.kbr.c2_to_main_baseline

        Update: I reran these 5 tests using a Mustang-B42 JDK with the
            Server VM:
                B42 VM - no failures
                20050623063809.sbohne.rt_merge - no failures
                20050623144856.kbr.c2_to_main_baseline - all 5 failed
            now from c2_baseline jobs:
                20050623143829.sgoldman.6288902 - all 5 failed
                20050623142908.never.c2 - all 5 failed
                20050623135529.jrose.mustang-intrinsics - all 5 failed
                20050623095333.sgoldman.6281185 - all 5 failed
                20050622194805.kbr.c2_baseline - all 5 failed
                20050622152338.jrose.mustang-intrinsics - all 5 failed
                20050622122040.kbr.main_to_c2_baseline - all 5 passed

            It looks like the failure was introduced with John Rose's
            PRT job 20050622152338.jrose.mustang-intrinsics.
