You have old versions of datanucleus-core and datanucleus-enhancer in the CLASSPATH somewhere. "OMFContext" from that stack trace hasn't existed in DataNucleus for a very long time.

I think I know, why it does not work to upgrade the appengine with a new datanucleus. It is not a classpath entry! I discovered that in the ant-macro.xml, which triggers the enhancing-step, there is a link to the appengine-tools-api.jar and there is the class EnhancerTask. This is probably a link to the old version since the new datanucleus-enhancer-3.0.1.jar has it's own EnhancerTask class. So the only way to use the new versions of datanucleus with the old appengine sdk (in contrary to http://code.google.com/p/datanucleus-appengine/wiki/HowToUpdateTheSDKWithANewPluginVersion) is to do the enhancement-step by either ant (https://developers.google.com/web-toolkit/doc/1.6/tutorial/appengine) or probably the eclipse-datanucleus-plugin. Unfortunately this plugin does not work properly in my Eclipse. After install/configure the plugin there is still no project-context menu "datanucleus", where I am supposed to add the support. So I'll try the ant version.
