Hi, I wanted to get rid of the stack locals from the jimple file by following command: java soot.Main -jb.a on,only-stack-locals:true -f jimple Test3 But the resulting jimple file still has stack locals like: $r1 = new Test3; specialinvoke $r1.<Test3. void <init>( )>( ); r2 = $r1; Could you please explain why its not working. Thanks Saswat
