what is wrong with this call to the java method?

Question

I am trying to call a Java method from the code. C code listens to either Escape, Shift, Ctrl key press, then it calls the Java method

Answer 1

I think it is due to the UAC feature enabled on your Operating System. This was a bug for Java 6. Read this for further reference.

The reason I say this is because the event to the escape key is fired correctly and the problem only begins as soon as the call to the java method is done.
