I tracked it down, although I still don't understand it! I had integrated EasyMock (easymock.org) to support some of my unit tests. In order for the unit tests to run, I needed to add asm (asm.ow2.org) and cglib (cglib.sourceforge.net) to my build path. If I remove these from my Eclipse build path, then my unit tests fail to run, but the server runs fine.
It looks like the solution is to maintain two separate build paths, one for unit tests that contains asm and cglib, and the other for regular development. I'd still love to know why including these on the build path would give a VerifyError. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
