/**
 * 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.
