result: Error. Program `c:\ade\mesos\work_dir\jib-master\install\jdk-18+14-734\windows-x64-debug.jdk\jdk-18\fastdebug\bin\java' timed out (timeout set to 1200000ms, elapsed time including timeout handling was 1303928ms).

Fix Request (11u): Should get backported for parity with 11.0.14-oracle. Follow-up fix for JDK-8271341. Fix from 17u applies cleanly (not problem listed in 11u, either, see previous comment).
07-10-2021
Fix request (17u): This fixes a test bug that was introduced by JDK-8271341. The fix is low risk and has been tested in the JDK 18 for a while and with tier1-3 in JDK 17u. The patch did not apply cleanly because I had to omit the changes to the ProblemList (the test is not problem listed in JDK 17u).
29-09-2021
The ProblemListing is in jdk-18+14-759. The fix for the bug is in jdk-18+15-769.

09-09-2021
jdk-18+14-734-tier7 now has a single sighting (so far) on linux-x64. Not as noisy as win-x64, but disappointing none the less since I've already ProblemListed the test on win-x64...
09-09-2021
7 instances (so far) on Win-X64 in jdk-18+14-734-tier7. This is rather noisy.
09-09-2021
The test task's JVM args for jdk-18+14-738-tier6 sighting are: -Xcomp -XX:+CreateCoredumpOnCrash -ea -esa -XX:CompileThreshold=100 -XX:+UnlockExperimentalVMOptions -server -XX:+TieredCompilation
08-09-2021
ILW = Test times out (test bug), single test with -Xcomp at tier6, no workaround = MLH = P4
08-09-2021
I think the problem is the newly added RepeatCompilation=100 which leads to an extrem slowdown of the test (especially with -Xcomp). Marking this as test bug.
08-09-2021
jdk-18+14-734-tier6 includes the following fix: JDK-8271341 Opcode() != Op_If && Opcode() != Op_RangeCheck) \|\| outcnt() == 2 assert failure with Test7179138_1.java for the same test. [~roland] do you mind taking a look at this test failure?
