JDK-8260555 - Change the default TIMEOUT_FACTOR from 4 to 1
Description
The hs_err file shows the SIGILL in the compiler thread due to a handshake timeout. However the core dump shows that the compiler thread encountered a signal whilst executring mprotect form within malloc, and it then gets repeated signals until presumably we get the SIGILL due to the timeout. Meanwhile maloc is unusable and all other threads lock up and the WatcherThread then tries to kill the VM. All in all a bit of a train wreck and no way to be sure what happened first. See comments for stack details.

I think what we are seeing here is simply the result of trying to apply the timeout handlers actions to the VM that has "crashed" as expected. We can see from the jtr log that the test actually completed successfully, but then the timeout handler was engaged. ----------System.err:(25/1364)---------- stdout: [[0.336s][error][handshake] Handshake timeout: ALotOfHandshakeClosure(0x00007f8595ffed40), pending threads: 1 [0.336s][error][handshake] JavaThread 0x00007f85bc02ea40 has not cleared handshake op: 0x00007f8595ffed40 # # A fatal error has been detected by the Java Runtime Environment: # # SIGILL (0x4) at pc=0x00007f85c4b2da92 (sent by handshake timeout handler), pid=1074000, tid=1074001 # # JRE version: Java(TM) SE Runtime Environment (26.0+15) (fastdebug build 26-ea+15-1475) # Java VM: Java HotSpot(TM) 64-Bit Server VM (fastdebug 26-ea+15-1475, mixed mode, sharing, tiered, compressed oops, compressed class ptrs, g1 gc, linux-amd64) # Problematic frame: # C [libc.so.6+0x98a92][thread 1074013 also had an error] [timeout occurred during error reporting in step "printing problematic frame"] after 30 s. # CreateCoredumpOnCrash turned off, no core file dumped # # An error report file with more information is saved as: # /opt/mach5/mesos/work_dir/slaves/7b1a61fd-59de-400e-939e-76c8ba818320-S93529/frameworks/1735e8a2-a1db-478c-8104-60c8b0af87dd-0196/executors/5ad7c2bc-717d-4fad-a407-27f12ca98cba/runs/d7cbf074-bd40-4280-94bd-7d2f7a81e43e/testoutput/test-support/jtreg_open_test_hotspot_jtreg_tier1_runtime_no_cds/scratch/4/hs_err_pid1074000.log # [ timer expired, abort... ] ]; stderr: [] exitValue = 134 JavaTest Message: Test complete. result: Error. "driver" action timed out with a timeout of 120 seconds on agent 28 I think this is simply a consequence of the timeout-factor change and we need to restore the original timeout value of 480 seconds. Whilst this test normally runs very quickly (< 1 s) we can also see it taking over 2 minutes - hence the reduced timeout would now kick in.
