compile to display java code line number

[Luke]

What parameters should I use to compile in order to display java code line number when exception ?  Below is error showing on my firefox when exception

uncaught exception: Class$S244: Exception caught: 2 exceptions caught: (TypeError)

If you run in devmode, you will see the Java line number.

To see something more easily understood in production mode, add -style PRETTY to your program arguments. See https://developers.google.com/web-toolkit/doc/latest/RefCommandLineTools, specifically targets gwtc and devmode generated by webAppCreator.

And don't forget <set-property name="compiler.stackMode" value="emulated"/> in that case.

Have also a look at the experimental SuperDevMode :)
