Sample Program:


public class BugDemo3 {
     public static void main(String argv[]) {
    }
}



To illustrate this, enter the following commands in jdb:


load BugDemo3
stop in BugDemo3.main
run BugDemo3
list main



java_g.exe terminates with an invalid memory reference.

Our Diagnosis

The crash is occuring in a call to
sun.tools.debug.getMethodLineNumber(). This API seems to be completely
broken.

We have tested this with the 1.1.2 beta JDK of 09APR97. It is still
broken.
