/**
 * This script traces method/block entry into every method of 
 * every class in javax.swing package! Think before using 
 * this script -- this will slow down your app significantly!!
 * Note tha Where.BEFORE is default. For synchronized blocks, BEFORE
 * means before "monitorenter" bytecode. For synchronized methods, we
 * can not have probe point Where.BEFORE. Lock is acquired before entering
 * synchronized method. By making the probe point Where.AFTER for SYNC_ENTER,
 * we probe after monitorenter bytecode or synchronized method entry.
