It looks like your compiler is having issues with the fact that getEmployee() throws an exception on the last line and doesn't return a value. Since the exception is thrown, no return value should be necessary.
To get it to compile, you can add this as the last line of that method:
Note that that line will never actually be executed.
I'm curious to know what compiler/verison you're using...
