Did you verify that everything still works after building Lilith with your changes?

Please don't get me wrong: everything looks fine for me and thanks for your contribution. It's really appreciated. The only problem is that I have no Windows to double-check for myself.

[tha2015]

Yes, I tested it on Windows under different situations:

1. Only JAVA_HOME is set
2. Only JAVA_EXE is set
3. Both JAVA_HOME and JAVA_EXE are set
4. None of JAVA_HOME or JAVA_EXE is set and javaw.exe is in PATH
5. None of JAVA_HOME or JAVA_EXE is set and javaw.exe is NOT in PATH

Of course you have to be careful about the quality. That's why I like to use this tool and want to help to improve it.

OK, thanks again. :)
