[Soot-list] JastAdd NullPointer

[Frank Otto]

Hi Eric,

my empty test class looks like this:

package test;
public class Test {
    public static void main(String[] args) {  } 
}

I use the command line parameters:
-cp
"C:/Programme/Java/jdk1.6.0_16/jre/lib/rt.jar;C:/Programme/Java/jdk1.6.0_16/
jre/lib/jce.jar;C:/Workspace/Test/src/test" Test

As said, using the Polyglot frontend (-polyglot option) works.

Thanks,
Frank
