I think the problem here may be that you have class names which are
different from the filenames that they are declared in (although the
compiler should pick this up...). I renamed "JavaHello.java" to
"JavaTool.java" and changed JavaMain::run to MainApp::run, then compiled
with the following command:

$ gcj MainApp.java JavaTool.java RunApp.cc --main=MainApp -o app -I.

... and it works fine:

$ ./app
Hello World from Java
