after updating to the newest release (20100319) of the eclipse plugin
(on 3/22), datanucleus enhancer is throwing null pointer exceptions
again. last time, it was due to classpath that was too long. removing
some unneeded jars out of my WEB-INF/lib directory seemed to do the
trick. this time, i cannot figure out what the problem is. i even
tried renaming jars to shorter names to no avail. PLEASE either (1)
fix this, or (2) give some kind of more detailed error message so we
know what is causing this.

furthermore, i cannot figure out how to rollback the google eclipse
plugin to the previous version. is this possible? if so, how?
