I'm running GWT 2.0, app engine 1.3, with Eclipse Galileo Build id:
20090920-1017, Java java-6-openjdk, on Ubuntu 9.10. Starting recently
-- within the past few weeks -- I started getting the error, "Unable
to contact the server" when I restart my GWT/app engine application
and reload the application's web page from Firefox. If I restart
Eclipse, it usually eliminates the problem temporarily, but not
always. This problem is sucking a significant amount of my time --
I've even had to reboot on occasion to make it go away. The exception
stack trace is below.
I'd really appreciate any ideas.
Thanks,
Rick
