You could try to run the 2.7 gwt servlet jar in the production env and the 2.8 
in the development env... this is for sure 100% not a supported solution, but 
it worked for me to get the 2.8 speed (in times until it was final) together 
with a 2.7 env :-)

Re: /rpc/RemoteService : Unsupported major.minor version 51.0

2017-01-01 Thread Kumarasamy R 
I just noticed that weblogic is still running at JDK 1.6. That might be the 
reason. It will be very hard for now to upgrade sdk on weblogic since other 
legacy applications are in same server.

Is there any alternate solution ?

Thanks
Kumar
