The Hudson web page attempts to access hudson.dev.java.net. Our development
network can not reach the internet, so the name does not resolve and the attempt
has to time out. Form submissions that take place before the call to
hudson.dev.java.net times out (such as configuring a slave or a job) return with
the following error:
Status Code: 400
Exception: This page expects a form submission
Stacktrace:

Aliasing hudson.dev.java.net to something like localhost lets the name resolve,
but it still takes a while for the connection to time out.

I believe the requests to hudson.dev.java.net are requests to get the available
versions of the JDK, Maven, and Ant (but since I can't get to the internet to
download them, this doesn't really help me). Is there a way to disable the feature?

I am currently having this issue with 1.319, but not with 1.295. I am having
this problem with Firefox 2 and 3.

Thanks.
