CMS: gc/gctests/FinalizeLock fails with SIGSEGV



    • Subcomponent:
    • CPU:
    • OS:


      Test gc/gctests/FinalizeLock intermittently fails on solaris10-x86 with options
      -client -Xmixed -XX:+UseConcMarkSweepGC

      Failure log is provided below

      It seems to me that this failure is similar to CR 6482915 and 6635560

      This bug is reproducible only with -XX:+UseConcMarkSweepGC option.

      ;; Using jvm: "/export/jdk/jdk1.6.0_19/jre/lib/i386/client/libjvm.so"
