Hi,
I ran the [SimpleVTK example](https://vtk.org/Wiki/VTK/Java_Wrapping) and encountered either crashes or warnings depending on the Java version. Are there existing workarounds to let VTK display java panels on MacOS + Java 14?
Not sure this may help, but I tried several combinations of MacOS+JDK with JOGL 2.3.2 and reported results [here](https://github.com/jzy3d/jzy3d-api/issues/128).
**MacOS Sierra (10.12.6) + AdoptOpenJDK14**
The Swing application crashes before displaying with the following messages in console

Thanks Sébastien!
I recently built a non official maven package of JOGL 2.4 version (RC was built in early 2021). It is a bit hacky (see [https://github.com/jzy3d/jogl-maven-deployer](https://github.com/jzy3d/jogl-maven-deployer)) but I was able to run it on a Jzy3D project. I noticed few regressions on Newt and Swing canvases, but AWT was working fine.
If you tell me where I can find JOGL jars in VTK Java SDK, I may give a try and see if the example better works with the recent JOGL 2.4 (2.4 is said to be retrocompatible with 2.3.2 that you probably use).

VTK does not hold those JOGL jars. We just point to then when building (I think) via CMake variables. But at the time I was using maven to fetch the jogl jar to run my VTK/java app/demo.

Thanks. I mainly wonder about the _runtime_ case. The java project I am working with does not explicitly include JOGL in its dependencies. It only include vtk.jar, the one that is generated while building VTK 9.0.3 with CMake. I wondered if it loads JOGL from my {home}/.m2/repository folder but renaming org/jogamp to org/jogamp\_ make it still able to start (and then crash 🙂)

I’m not sure.
