--------------F35CB4FABBFA66B0E9D2A8E8--
See attached file.
We've spent a lot of time tracking down this problem and
are at a dead end. Basically, we had related problems with jdk 1.2
but found that 1.4 beta1 seemed to solve the problems.
We recently tried 1.4 beta 2 and the problem resurfaced.
We have a program that, if we run it for a couple of hours, seems to reliably
reproduce the problem, but it's a big messy thing to run and not readily
packaged up. Hopefully, the info below might be useful to someone.
Also, I'd like to volunteer to be in the loop to test 1.4 beta 3.
If we could get a pre-release of this, we can run it thru our program to see
if this race is still there.
Anything you can do to help would be appreciated; we'd go thru the normal
bug voting process but the steps to reproduce this are not possible to
list in any compact way.
Thanks,
    jon

Version info:
java -version
    java version "1.4.0-beta2"
    Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta2-b77)
    Java HotSpot(TM) Client VM (build 1.4.0-beta2-b77, mixed mode)
uname -a
    SunOS build 5.7 Generic_106541-17 sun4u sparc SUNW,Ultra-60

Symptom: A jvm wedged. Not consuming any CPU or doing any I/O. Would seem to
be a deadlock, but a stack dump implies that threads are blocked in native
methods from the java runtime that "shouldn't" be blocked.

The problem seems to be triggered by a rare race condition. We have to run our
application system for an hour or two before it happens. It is always the same
java application that hangs, but that application may run numerous times
without problem before eventually hanging.

The problem only seems to arise in jdk1.4-beta2; beta1 works fine.

Four dumps (obtained by sending SIGQUIT to the jvm) are attached to this
message. In two of them two threads are stuck in
java.io.UnixFileSystem.getBooleanAttributes0. In each of the other two, one
thread is in sun.misc.Launcher$AppClassLoader.loadClass and another is in
java.util.zip.Inflater.inflateBytes. In all but one case, both suspect threads
are in the class loader. In the last case, one of the threads is in
ClassLoader and the other is simply calling java.io.File.isDirectory from
application code.

I have a core file obtained with gcore from one the runs (one that was stuck in
getBooleanAttributes0). If you want a copy of it, let me know (it's about
10MB). According to gdb, the threads wedged in getBooleanAttributes0 have this
at the top of their stacks:
