Getting Unexpected internal compiler error

Hi All,

I am new to GWT and I imported existing Web GWT project to Eclipse and when i try to compile it through "GWT Compile" option of Eclipse it is throwing below error.

Project looks to be properly set up in Eclipse Workspace.

I am using GWT 2.7.0.

Can anyone please help in resolving below exception?
