com.google.gwt.dev.jjs.InternalCompilerException

Unexpected error during visit.

Samebug tips4

A few things cause this exception: 1) Check if you have all jars and if they're in the correct path when running. 2) Your classpath might be broken, you can define it in the command line with "java -cp yourClassPath" or at your IDE if you're using one.

Needs to add netty-transport-native-epoll with a OS classifier to the classpath, it's not included in netty-all
