java.lang.VerifyError can be the result when you have compiled against a different library than you are using at runtime or there had been changes to the classes and methods, so that the method signatures found at runtime did not match what was there at compile-time.

I would suggest making sure you do a full clean of the project and also checking the build path contains all the right libraries and configurations.
