Play framework 1.2.7.x with Java 1.8

Is Play framework 1.2.7 supported with java 1.8? I am able to precompile the application but it fails with the following error on start

Maybe this answer is coming to late but... As far as I know there's no java 8support for 1.2.X but following this answer: Play framework 1.x with java 8 You could easily move to 1.3 and use that solution. I just did a migration from 1.2 to 1.4 without big issues.
