I'm using the Google Plugin for Eclipse, today i encountered a similar
problem and solved it.
opened the debug-level log, if you find the following text, remove the
gae library and re-add it.
DEBUG [org.datanucleus.util.Log4JLogger.debug(Log4JLogger.java:58)]
Class "org.eclipse.core.runtime.Regis
i have similar problem and it looks like this happens because of
failed enhancement. actually the log which was mentioned in the
message does not exist (or i can't find it) and i still do not know
how to make it work.
enhance:
DataNucleus Enhancer (version 1.1.0) : Enhancement of classes
DataNucl
