VerifyError; Expecting a stack map frame in method controllers.Secure$Security.authentify

Question

I followed the tutorial introducing the Play framework, but it gives me an error:

Execution exception VerifyError occured : Expecting a stack map f

Answer 1

The message group for Play has discussed that there are some issues with JDK1.7, and that Play does not officially support this yet. If possible, please try with JDK 6, and see if you still get this error.

If you are confined to JDK7, you can use the option

java.source=1.6

in your application.conf file.

Update 18th August 2011: Nicolas Leroux recently sent out a message on Twitter to say that Java 7 support had been added to Play in the master branch. It probably won't make the 1.2.3 release, but will make the release after that.
