A sighting in nightly testing:

New MM_REGRESSION failures (from 2009.02.24)
* java/lang/management/ThreadMXBean/ThreadCpuTime.java
        This test failed the following assert:

            Internal Error (src/share/vm/runtime/compilationPolicy.cpp:104)
            Error: assert(!m->was_never_executed(),
                "don't reset to 0 -- could be mistaken for never-executed")

        on Win-AMD64 Server VM -Xmixed (machine intelsdv14). This is an
        occurrence of the following bug:

            6805748 2/2 Assertion "don't reset to 0 -- could be
                        mistaken for never-executed" in CompilationPolicy

        I will copy this entry to 6805748.
