I'm moving from 0.6 to 0.61 trunk and am getting the following error? I'm guessing I need to change some dependency in project.xml, but I'd like to know the root cause to avoid it in the future.

It looks like a Spring version issue, but I don't think the versions have changed. Thanks.

Code:

49.0 is the class file version for JDK 1.5.0 - this error is probably caused by building with 1.5 and deploying on a 1.4 JVM.
