[Soot-list] Soot class instance

[Satyaditya Munipalle]

Hi Mr.Eric,
                     I am trying to instrument my android app using soot .I
am trying to assign a local variable to a class object so that i can call
the methods of the class using it. I had noticed that my jimple output the
<init>  is not being called
 JAVA CODE:

Scene.v().loadClassAndSupport("record.Structure");
 SootClass structClass=Scene.v().getSootClass("record.Structure");
SootMethod setGenericParams   = structClass.getMethod("boolean
setGenericParams()");
                               In the chain iterator I am trying to create
an instance of the class. I had created the local as shown below

                              Local structLocal = Jimple.v().newLocal("$r"
+ locals.size(),structClass.getType());
 locals.add(structLocal);

//initializing struct class
 Value rValue=Jimple.v().newNewExpr(RefType.v(structClass));
Stmt newAssignStmt = Jimple.v().newAssignStmt(structLocal, rValue);
 logBlock.add(newAssignStmt);
units.insertAfter(logBlock, stmt);



JIMPLE REPRESENTATION
                     $r13 = new record.Logger;
                    $r12 = new record.Structure;
                   specialinvoke $r12.<record.Structure: boolean
setGenericParams()>();  //NO INIT BEING CALLED
                   specialinvoke $r13.<record.Logger: void
log(record.Structure)>($r12);


and  I am running into this particular error after writing this piece of
code.
Exception

Exception in thread "main" java.lang.Error: unknown SpecialInvokeExpr (no
call to constructor, super or private method): specialinvoke $r12.

at soot.PackManager.writeOutput(PackManager.java:595)

Is this the right way of creating an object for a class?? Please help me

adit.
