This is the initial release of my VisualVM integration plugin. As far as I know, this is the first free Java profiler available for IDEA. There are still quite many issues and missing features (see the project page), but it's already possible to profile the CPU usage of programs launched from within IDEA.
Description: Launches VisualVM's Java profiler from within IDEA. VisualVM is based on NetBeans Profiler and it is bundled with JDK 6 Update 7 and above. VisualVM may also be downloaded separately from https://visualvm.dev.java.net/
