Exception in thread \"main\" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type:

Answer 1

The code you provided runs fine on my computer.

I'm guessing you are using Netbeans and may be affected by a bug. Try this:

Open the project properties, select the Build-Compiling, uncheck "Compile on save" and rerun the application. This will make sure all your source code becomes recompiled before running it.
