OpenJDK - Debugging Tools like VisualVM for JDK 1.8

[Matthew Henry]

Hi,

What are the debugging tools available in OpenJDK - Debugging Tools like VisualVM for JDK 1.8

Thanks

[Tim Moores]

VisualVM works with just about any JDK, certainly with Java 8 and newer.

Other tools can be found at https://openjdk.org/tools/

Conversely, you can do visual debugging with just about any IDE, including Eclipse, IntelliJ and NetBeans.

The latest VisualVM release supports Java 21 (presumably OpenJDK, Oracle and other recent JVMs).

I would hasten to migrate away from Java 8, though. It uses an now-obsolescent introspection architecture and that can cause issues when building apps using more modern libraries.
