Java EE (Java Enterprise Edition) General Discussion

Within the last few days our build process has been failing quite sporadically. Actually, it's failing more times than it succeeds.
We are using an ATG application and part of the ant build process uses an [assemble-jar] task. However, this task is failing with "[assemble-jar] java.net.ConnectException: Connection timed out: connect"
Digging into it some more, it looks like it is failing during DTD validation and having trouble connecting to http://java.sun.com/ to pull the appropriate DTDs.
Sometimes it works, but most times it doesn't.

Then I just tried going to http://java.sun.com in my browser and noticed it timed out. I tried several more times and once it redirected to oracle.com but the other times they also timed out.

Has anyone else experienced this issue with java.sun.com in general, and with DTD validation specifically? Any workarounds? Anyone know if Oracle is working on the issue?

Thanks!
