JDK 1.6 update 7+ is delivered with visualvm; a powerful monitoring and profiling tool. Visualvm comes with a profiler, which is actually part of Netbeans. Visualvm is a Netbeans RCP application (about 10 MB), which can be extended with Netbeans modules / plugins. So Netbeans RCP becomes ubiquitous :-).
