More information to make this puzzle even more confusing.

1) I have an (apparently) identical setup on a second machine that works without

this error. Both machines are the same hardware, OS, jdk, apache, tomcat
versions.

2) Also I'm fairly sure this is not a file not found error, because I tested it
on the
machine where it is not present and could not get it to duplicate based on the
file not existing.

I was able to get an identical stack trace by telneting into the
port for webapp and killing the connection (however).

I've searched over the archived mailing list and seen this issue a few
times, but never a resolution.

Does it only happen to a very very very few people?

There is probably a very simple explanation that I am missing :-(

Also when the 'Application not currenlty deployed' error page is
displayed it shows the full path to the webapp.c file in the title
for the page (definately a feature, but possibly a dangerous one)...
