Hudson build fails with Maven JVM terminated unexpectedly with exit code 134

Thu, 16 Dec 2010 01:09:00 GMT

We use Hudson as a continuous integration tool for Twitter4J.
I really love the maven oriented and easy to use tool and it makes Twitter4J development much smoother.

But what unfortunate is the error message "ERROR: Maven JVM terminated unexpectedly with exit code 134" which can be seen quite often. This is really annoying because it happens randomly and when it happens, it persists until I restart Hudson.

I consulted the mailing list and knew that exit code 134 indicates that the process crashed with SEGV or something like that.
But somehow I don't couldn't find hs_err_pid[PID].log or core dump on the current directory.
Then I dug an important message from syslog, saying

Nov 25 21:59:17 macmini com.apple.ReportCrash.Root[3736]: 2010-11-25 21:59:17.966 ReportCrash[3736:1407] Saved crash report for java[3732] version 1.0 (1.0) to /Library/Logs/DiagnosticReports/java_2010-11-25-215917_localhost.crash

It seems that Apple's JVM stores crash reports under /Library/Logs/DiagnosticReports/ as same as other native OSX apps.
Here's snippet of the crash report:

Thread 0 Crashed: Dispatch queue: com.apple.main-thread

17 java 0x00000001000017b4 0x100000000 + 6068

From the stack, I can see that the JVM crashed while initializing AWT and it appears to be a Mac OSX specific issue.

Then I googled with "AWTStarter crashed __NSThreadPerformPerform java com.apple.main-thread GetOurLSSessionIDInit" and found this thread.
・Comments about Nasty problem with headless mode in Tomcat 6-0-24

In fact just after receiving this email from you I also got one from
Apple saying that it's a bug and that they're trying to solve it.

The above thread doesn't tell any solution or workaround, but the subject hints that it happens only on headless mode.
So I turned -Djava.awt.headless=false to true and the problem solved, yay!

Things learned from the issue:
- usually exit code 134 is caused by SEGV
- Apple's JVM dumps crash report to /Library/Logs/DiagnosticReports/java_YYYY-MM-DD-******_[hostname].crash
- Apple's JVM dies with code 134 occasionally and it's a known issue
- the issue can be workarounded with -Djava.awt.headless=true (or just without -Djava.awt.headless option)
