问题 When I export the default libgdx project as a runnable JAR file from eclipse and then run the .jar file, it simply pops up a black screen and then closes. When I run the project code from inside Eclispe, it works fine. The correct red screen with the "bad logic" logo is displayed by the program (this is what is supposed to happen).

问题 I have a jar that contain a class that I would like to modify. For some reason I do not want to re-compile and update the Jar. So what I do is I recreate a full qualified name for that class in my project, and place my code in it, but I do not have an idea how to ensure JVM loaded my project class and not the Jar class.
