You can start VisualVM 2.0 on OpenJDK 14 using
visualvm -J-Dorg.graalvm.visualvm.modules.startup.DisableStartupCheck=true
This disables the JDK version check for unsupported JDK.

We plan to add support for JDK 14 in the near future.

Thank you for workaround!
Is there a way to apply this workaround so that it would be possible to launch VisualVM as an app from Finder, not as process from Terminal?

Partially related to issue #160

You can create <your_user_directory>/etc/visualvm.conf file with the following content:

visualvm_default_options="-J-Dorg.graalvm.visualvm.modules.startup.DisableStartupCheck=true ${visualvm_default_options}"

Your user directory is available via VisualVM->About VisualVM->Details.

Sadly, it didn't work for me...
May I suggest a small UX enhancement? Maybe in the "Error Starting VIsualVM" dialog there could be second button "Ignore and start" - which would rerun startup logic while ignoring JDK check?

Or just use a supported jdk version, example:

# ~/Library/Application Support/VisualVM/2.0/etc/visualvm.conf
visualvm_jdkhome=/Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home

And make sure to point it to the version you have installed.

VisualVM 2.0.1 (with JDK 14 support) was just released. Closing.
