[Soot-list] Execute several Soot runs in batch mode

[Mario Mendez]

Hi all,

I'm trying to execute several times the same Soot transformation, in 
order to calculate an average of how much time does my compilation take. 
I'm trying to do it with a Java program, a 'main' that given some 
arguments and after adding my BodyTransformation invokes soot.Main in a 
loop:

	public static void main(String[] args) {
		//get actual time
		for (int i=1;i<5;i++){
		    PackManager.v().getPack("jtp").add(new 
Transform("jtp.pl",CiaoGenerator.v()));
    		    soot.Main.main(args);			
		    CiaoGenerator.v().finalize();
		}
		//get actual time
	}

This raises an error because of Options trying to parse the same 'args' 
many times. Therefore, I took a look at soot.Main and changed the code 
above to

	public static void main(String[] args) {
		//get actual time		PackManager.v().getPack("jtp").add(new 
Transform("jtp.pl",CiaoGenerator.v()));
		soot.Main.main(args);			
		CiaoGenerator.v().finalize();		
		for (int i=1;i<5;i++){
	            PackManager.v().runPacks();
	            PackManager.v().writeOutput();
		    CiaoGenerator.v().finalize();
		}
		//get actual time
	}
But this also raises an error

Exception in thread "main" java.lang.NullPointerException
	at soot.SootMethod.getBodyFromMethodSource(SootMethod.java:82)
	at soot.SootMethod.retrieveActiveBody(SootMethod.java:329)
	at soot.PackManager.retrieveAllBodies(PackManager.java:958)
	at soot.PackManager.runPacks(PackManager.java:328)
	at soot.CiaoMain.main(Unknown Source)

I'm using Soot 2.2.4. Any idea about how to run Soot several times in a 
row? I would really like to avoid using shell scripts to do it


Thanks!
