[play - 1.2.7] Java 1.8 issues (play.classloading.enhancers.ContinuationEnhancer)

[dhar...@scalegrid.io]

Hi folks,

Is java 1.8 supported for play 1.2.7? I am moving my application from Java 1.6 to 1.8. I am able to precompile the application but get errors trying to run it. Any help or pointers are appreciated.

Hi

No, it's not. You have to upgrade to 1.3.x

Thanks for the update. Is java 1.7.x supported?

 It will be good to add the last supported JVM version to the documentation for each release.
