New performance tool for IBM JVM

(Un)Fortunately I have to work with a IBM Java environment (PPC64 hardware), and I have to say that the big blue provides several tools to diagnose problems. One of those tools is the Java Lock Analyzer. It allows a developer to detect and diagnose lock and monitor problems such as deadlocks or unnecessary wait states.
BTW, it only works with IBM JVMs AFAIK.
Hope it helps.
