[Soot-list] JastAdd NullPointer

[Frank Otto]

Hi list,

I plan to develop analyses using the latest soot-2.4.0 runnable JAR. For
this purpose, I have a main class ("empty" so far) referencing that JAR:

import soot.*;
public class MyAnalysis {
	public static void main(String[] args) {
		soot.Main.main(args);
	}
}

When I run it for an empty test class (standard configuration, using the
JastAdd frontend), I get the following NullPointerException:


-----
Soot started on Wed Nov 10 10:10:15 CET 2010 java.lang.NullPointerException

When I run it with the -polyglot option, it works fine:

Soot finished on Wed Nov 10 11:54:09 CET 2010 Soot has run for 0 min. 1 sec.

What did I do wrong with JastAdd? Sorry if this (probably simple) question
was already discussed somewhere, I haven't found anything related...

Thanks,
