Subject Re: buildbot failure in ASF Buildbot on tomcat-trunk
Date Sun, 01 Jan 2012 03:11:09 GMT
I haven't tried to reproduce it yet. The following is from buildbot's
stdout file:

Both BIO and NIO fail the same test:
    [junit] Tests run: 7, Failures: 4, Errors: 0, Time elapsed: 0.175 sec
    [junit] Test org.apache.catalina.startup.TestWebRuleSet FAILED

BTW, during the NIO run there are several NPEs like the following:

It is hard to tell to what test these NPEs belong. I suspect that they
occur during shutdown.
