Collection of Java procps-like utilities (such as top, ps, etc)

jtop is the only tool currently implemented, providing a top-like interface for visualizing CPU usage of Java threads. This is intended to give you a clue what to look for when troubleshooting very large or complex multi-threaded Java applications using jconsole or a traditional debugger. Looking at you, IntelliJ.

jtop works by simply combining ps and jstack and providing a similar UI to top.
