JIP: IBM developerWorks article

IBM developerWorks has published an article by Andrew Wilcox (the principle developer of JIP -- the Java Interactive Profiler) about building a Java profiler using the Java 5 Agent interface. JIP embodies all of the desirable qualities of a Java profiler, as laid out in the article, in the form of a mature, Open Source product.
