Heya,
I'm running into an issue were the sablevm seems to be hanging on what i
think is a threading related issue. I've narrowed down where in code
the hang occurs, but i'm not sure _why_ it occurs. I'm providing the
class and instantiation along with a portion of strace output. if more
strace output would help, please let me know.
Any help would be greatly appreciated.
System config:
Suse 9.1 updated; x86
Thanks,
Joe

Hi Joe,
Could you also type Ctrl-\ [e.g. SIGQUIT], when it hangs? This would
dump the Java stack trace.

Hi Joe,
It's obviously a deadlock somewhere, which means a concurrency /
threading bug. It could either be in Classpath or in our locking code.
AWT is not really something I know about. Greg recently implemented
InterruptedException IIRC, and that could be it as well.
Can you reproduce the problem without AWT? Is that really the absolute
simplest test case you can give us? What happens if you declare the
Thread body as a named class? Does it happen every single time?
Cheers,
Chris

I've done some testing with sablevm and calling methods for awt, and i
haven't had a problem. For example, instantiating an AWT or Swing class
from inside another class there were no problems. If i remove that call
in code, it then hangs on the instantiation of an AWT/Swing class one line
later. The hang happens every time (and i've tried about 40+ times to
make sure ;p). I'm really not sure why it would hang there, and i know
there is no problem using Sun's jvm.
I'm not too familiar on how your vm works. Do you create a thread per
class that's loaded, etc? I wish i had a more simple test case to work
with. What are the relevant files i should be looking at? I will
continue to try and replicate this problem in a more simple case.

Check out the staging versions of sablevm and sablevm-classpath (which are fairly stable, but contain more recent updates than the tarballs). You could also grab the latest nightly snapshots. See: http://devel.sablevm.org/wiki/Getting As for relevant files ... well, there's Java stuff in sablevm-classpath, and VM stuff in sablevm. You might want to try ./configure --enable-debugging-features --with-threading=switch for the most safe mode. The switch interpreter is easier to step through with gdb. I tried it with an older (roughly 1.1.4) sablevm-switch-debug and it still hangs.

Sure. Basically every line or possibly funny syntax (e.g. anonymous classes) that you can eliminate cuts down the problem. Cheers, Chris |

Yeah, i made that sounds confusing ;p I meant to say that i have no problem using the AwtUtils.init... by itself, nor do i have a problem burying an awt class way down in a series of class instantiations (currently tried about 6 levels down). However, in the current code base (JXTA) if i remove the call to AwtUtils.init... the next call (which instantiates a class that displays a Frame) hangs with the same problem and at VMObject.wait. I'm not sure if i'm hitting a thread limit or what, it seems kind of odd that the same problem occurs regardless of whether or not i call AwtUtils.init or create a new Frame. I'll try your suggestions below and post some results. Thanks!

Let's work from the AwtUtils.java that I modified to have a main() method. It runs with Sun's JDK but hangs with sablevm AFAICT. Try and simplify just that until it doesn't hang, and give us the minimal hanging example. For example, you can remove the "f.dispose();" line and it will still hang, but not the "Frame f = new Frame();" line. Cheers, Chris |

I'll have to second that. I've ran through some code and the f.dispose does seem to finish and return, and it does seem the thread isn't being destroyed (otherwise the vm should exit). Is it possibly something in the Window.dispose code that's confusing the VM? I've only gone so far as to gurantee that each call is completing, but not actually tracing each call. I also found that removing this call in Window.dispose: getToolkit().getSystemEventQueue().postEvent(we); seems to allow the engine to exit after completion. I'll have to do further testing to verify that's really what's causing the problem, but it seems so at first glance. --Joe On Fri, 18 Jun 2004, Chris Pickett wrote: > Chris Pickett wrote: > > Joseph Paris wrote: > > > >>Yeah, i made that sounds confusing ;p I meant to say that i have no > >>problem using the AwtUtils.init... by itself, nor do i have a problem > >>burying an awt class way down in a series of class instantiations > >>(currently tried about 6 levels down). > >> > >>However, in the current code base (JXTA) if i remove the call to > >>AwtUtils.init... the next call (which instantiates a class that displays a > >>Frame) hangs with the same problem and at VMObject.wait.

Hi Joe, (Etienne, can you read and comment?)
So, if you look at gdb stacktraces for each process, you can see exactly
how it's deadlocking:
$ ps -A u
...
cpicke 455 1.0 0.1 25456 3436 pts/0 S 13:31 0:00
sablevm-switch-debug AwtUtils2
cpicke 457 0.0 0.1 25456 3436 pts/0 S 13:31 0:00
sablevm-switch-debug AwtUtils2
cpicke 458 0.0 0.1 25456 3436 pts/0 S 13:31 0:00
sablevm-switch-debug AwtUtils2
...
It seems from instruction traces that actually 455 is the MyThread
thread, 457 I'm unclear about, and 458 is the AwtUtils2.main() thread.
What's confusing is that the AwtUtils2.main() thread has thread.id == 2,
whereas the MyThread has thread.id == 1. I put a
'System.out.println("hello");' in MyThread to be sure -- you only see
the calls to it in T1 (grep println AwtUtils2.log).
http://www.sable.mcgill.ca/~cpicke/sablevm/AwtUtils2.java
http://www.sable.mcgill.ca/~cpicke/sablevm/AwtUtils2.log (69M)
If I understand correctly, the AwtUtils2.main() thread starts the
MyThread, waits for it to die, and in the meantime the MyThread tries to
exit the VM itself, because of a mishandled:
getToolkit().getSystemEventQueue().postEvent(we);
in java.awt.Window.dispose() like you said.

if (ms == 0 && ns == 0)
{

}
--> this is the AwtUtils2.main() thread (AFAICT)
Anyway, I don't know what the solution is. I originally thought
broadcasting to all sleeping threads when trying to exit the VM was the
answer, but now I'm not sure.
Cheers,
Chris

Sorry for all the emails on this, but this just occurred to me: re-reading http://java.sun.com/j2se/1.4.2/docs/api/java/awt/doc-files/AWTThreadIssues.html it seems like it's not a SableVM but a Classpath AWT problem, in that Classpath AWT does not terminate its helper threads, whereas it should (if it were to support 1.4, that is). If you look, there are three conditions to be satisfied: 1) There are no displayable AWT or Swing components. 2) There are no native events in the native event queue. 3) There are no AWT events in java EventQueues. I think the fix is for java.awt.EventDispatchThread.run() to test all three conditions and terminate itself if all true. Cheers, Chris |

I should also mention that it hangs in the same place at:
(VMObject.java:-1) java/lang/VMObject.wait n
I was curious as to why it references '-1'.
