      Description

        Jim reported a couple of more:

        Two of these assertions in Sept:

        /java/sqe/results/vm/gtee/JDK7/NIGHTLY/VM/2008-09-01/G1_GC_Baseline/vm/solaris-sparcv9/server/mixed/vm-solaris-sparcv9_server_mixed_nsk.stress.testlist2008-09-01-23-56-06/ResultDir/except007/except007.log:[2008-09-02T12:43:43.34] # Error: assert(new_obj != 0L || obj->mark() == markOopDesc::prototype() || (UseBiasedLocking && obj->mark()->has_bias_pattern()) || obj->is_shared(),"should be forwarded")

        The above test is:

            nsk/stress/except/except007


        /java/sqe/results/vm/gtee/JDK7/NIGHTLY/VM/2008-09-18/G1_GC_Baseline/vm/windows-i586/client/mixed/vm-windows-i586_client_mixed_nsk.stress.testlist2008-09-19-00-04-54/ResultDir/except001/except001.log:[2008-09-19T08:47:43.72] # Error: assert(new_obj != 0 || obj->mark() == markOopDesc::prototype() || (UseBiasedLocking && obj->mark()->has_bias_pattern()) || obj->is_shared(),"should be forwarded")

        The above test is:

            nsk/stress/except/except001
        Here is an entry from my nightly analysis report:

        New JDI_REGRESSION failures (from 2008.10.02)
        * com/sun/jdi/FinalizerTest.java
                This test failed the following assert:

                    Internal Error (src/share/vm/gc_implementation/shared/
                        markSweep.inline.hpp:90)
                    Error: assert(new_obj != 0
                        || obj->mark() == markOopDesc::prototype()
                        || (UseBiasedLocking && obj->mark()->has_bias_pattern())
                        || obj->is_shared(),"should be forwarded")

                on Solaris X86 Server VM (machine vm-b1600x-8). This test is
                covered by the following bug:

                    6609520 4/3 com/sun/jdk/FinalizerTest.java failed

                However, 6609520 does not cover this failure mode.
