[JBoss-dev] jboss-head minimal server fails to shutdown

[Ryan Campbell]

We are seeing failures in the jboss-head testsuite where the minimal
server fails to shutdown.  This is not happening on the build server,
but we are seeing the problem in both Windows and Linux outside of the
QA lab.

There are two potential manifestations of the problem.  One is a debug
message from the NamingService about a broken pipe.  The other is an
infinite loop in the unifiedclassloader upon shutdown.  

We are not sure if there is a relation between these two stack traces,
or if the first stack trace is even an error.

Is anyone else seeing this?

Stack overflow (certainly seems to be the cause):

Hi All

I just downloaded the new version of jboss-head and tried to run the
testsuite, and got the same problem. The changes which Anil made are
visible in the output:

> ./build.sh tests
