A lot of tests failed in "-server -Xcomp" on solaris-amd64 using fastdebug bits. The tests mostly fail with java.lang.NullPointerException or java.lang.NoClassDefFoundError. The tests don't fail with -Xint or -Xmixed, with client compiler, previous jdk7/hs14 builds and don't fail on other platforms. Entries for this failure mode from my nightly analysis report: New nsk.jvmti.unit failures (from 2008.12.16) * nsk/jvmti/unit/ForceEarlyReturn/earlyretlong * nsk/jvmti/unit/ForceEarlyReturn/earlyretstr earlyretlong failed due to: Falure: wrong value returned: 0 and earlyretstr failed due to: Expected string: "Expected String" Returned string: "null" on Solaris AMD64 Server VM (machine vm-v20z-7). These tests have not failed before this nightly when earlyretbase and earlyretint failed. See nsk.jvmti entry on 2008.12.09 for more details. New nsk.jvmti failures (from 2008.12.09) * nsk/jvmti/scenarios/hotswap/HS101/hs101t001 * nsk/jvmti/scenarios/hotswap/HS101/hs101t003 * nsk/jvmti/scenarios/hotswap/HS101/hs101t004 * nsk/jvmti/scenarios/hotswap/HS101/hs101t006 These tests failed due to "ERROR: Wrong number[40]: 5702887, expected: 102334155" (for example) on Solaris AMD64 Server VM (machine vm-v20z-6). This failure mode matches the following bug which was fixed in Mustang-B82: 6415119 3/4 REGRESSION: hs101t001, hs101t003, hs101t004, PopSynchronousTest, RedefineCrossStart Update: These tests passed in the 2008.12.08 nightly. Update: These tests passed in the 2008.12.10 nightly, but failed again in the 2008.12.11 nightly. 12.08 and 12.10 nightlies used -XX:+UseCompressedOops and the 12.09 and 12.11 nightlies used -XX:-UseCompressedOops. The last -XX:-UseCompressedOops nightly where these tests passed was on 2008.12.06. I merged with jdk7/hotspot/hotspot on 2008.12.08 and picked up 2008-12-05-201045.ls199021.hotspot and 2008-12-05-234952.et151817.hotspot. Erik's job was just tags and hotspot_version changes so this might have come from Lev's push. I checked the RT_Baseline results for 2008.12.06 and the failures did not reproduce there, but RT_Baseline is run with -Xmixed instead of -Xcomp. New nsk.jvmti.unit failures (from 2008.12.09) * nsk/jvmti/unit/ForceEarlyReturn/earlyretbase * nsk/jvmti/unit/ForceEarlyReturn/earlyretint earlyretbase failed due to: Returned result: 0 Wrong result returned and earlyretint failed due to: Falure: wrong value returned: 0 on Solaris AMD64 Server VM (machine vm-v20z-9). Update: These tests passed in the 2008.12.08 nightly. Update: See previous entry for more details.
