I have been getting this exception when trying to Run
XDoclet with JBoss-IDE 1.4.0 and Eclipse 3.0.1.

It turns out there is a conflict between the JBoss-IDE
plugin and the Rational ClearCase SCM Adapter 6.0.24
plugin. Becuase this plugin is "always on", we can't turn
the plugin off. We have to disable the plugin to turn it
off. I disabled the plugin and I was able to run xdoclet
every time. As soon as I re-enabled the plugin. Run
XDoclet stopped working.
