Incompatible object argument for function call

Hi,

Am here again on some issue. Getting this error "Incompatible object argument for function call"


Here is what I'm trying to do. On method entry, I call a method to pass on the method details & parameters.

        Label startLabel = new Label(); Label endLabel = new Label(); Label exceptionLabel = new Label(); mv.visitTryCatchBlock(startLabel, endLabel, exceptionLabel, "java/lang/Throwable"); mv.visitLabel(startLabel); mv.visitMethodInsn(INVOKESTATIC, "test/MyClass", "getInstance", "()Ltest/MyClass;"); mv.visitLdcInsn(tracerName); mv.visitLdcInsn(className); mv.visitLdcInsn(methodName); mv.visitLdcInsn(methodDesc); loadArgArray(); mv.visitMethodInsn(INVOKEVIRTUAL, "test/MyClass", "invoke", method_desc); mv.visitLabel(endLabel); Label doneLabel = new Label(); mv.visitJumpInsn(GOTO, doneLabel); mv.visitLabel(exceptionLabel); mv.visitFrame(Opcodes.F_SAME1, 0, null, 1, new Object[] { "java/lang/Exception" }); mv.visitVarInsn(ASTORE, 1); mv.visitVarInsn(ALOAD, 1); mv.visitMethodInsn(INVOKEVIRTUAL
 , "java/lang/Throwable", "printStackTrace", "()V"); mv.visitLabel(doneLabel); 

In on method exit:


 try { if(opcode != ATHROW) { onFinally(opcode); } } catch(Exception ex) { ex.printStackTrace(); }


private void onFinally(int opcode) { Label doneLabel = new Label(); if(opcode == ATHROW) { dup();     Type eType = Type.getType(Throwable.class); int exception = newLocal(eType); storeLocal(exception, eType); mv.visitMethodInsn(INVOKESTATIC, "test/MyClass", "getInstance", "()Ltest/MyClass;"); loadLocal(exception); mv.visitMethodInsn(INVOKEVIRTUAL, "test/MyClass", "finish", "(Ljava/lang/Throwable;)V"); } else { Type returnType = Type.getReturnType(methodDesc);
            Type objectType = Type.getObjectType("java/lang/Object"); int returnVar = -1; if(opcode != RETURN) { if(opcode == LRETURN || opcode == DRETURN) { dup2(); } else { dup(); } loadReturnValue(returnType); //this loads the primitive return value as object in the top of the operand stack returnVar = newLocal(returnType); storeLocal(returnVar, returnType); box(objectType); } mv.visitMethodInsn(INVOKESTATIC, "test/MyClass", "getInstance", "()Ltest/MyClass;"); mv.visitIntInsn(SIPUSH, opcode); if(opcode == RETURN) { mv.visitInsn(ACONST_NULL); } else { loadLocal(returnVar); } mv.visitMethodInsn(INVOKEVIRTUAL, "test/MyClass", "finish", "(ILjava/lang/Object;)V"); } visitLabel(doneLabel); }

I know I'm missing something here. I tried hard but in vain. 


Any help is much appreciated.


Thanks,
