“Illegal reflective access by com.jogamp.common.os.NativeLibrary” when using P3D (caused by JOGL)

[sampottinger]

Filing for kll from a processing forums discussion. The following happens when using P3D:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.jogamp.common.os.NativeLibrary$3 (file:/.../core/library/gluegen-rt.jar) to method java.lang.ClassLoader.findLibrary(java.lang.String)
WARNING: Please consider reporting this to the maintainers of com.jogamp.common.os.NativeLibrary$3
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

This comes from JOGL itself and is related to JEP 261 as tracked at https://jogamp.org/bugzilla//show_bug.cgi?id=1363. There is no resolution on the Processing side except for moving to LWJGL or waiting for an update from JOGL. I believe @codeanticode is looking into LWJGL.

@sampottinger indeed, I created a fork from your earlier processing-openjdk repo that uses LWJGL for the core OpenGL renderer:

https://github.com/codeanticode/processing-openjdk/tree/lwjgl-renderer

It still needs some work to encapsulate all AWT dependencies so they are not used when launching a sketch with the P2D or P3D renderers.

@codeanticode that's not quite correct. There is only a requirement to encapsulate aspects of AWT that can't work headless, is much less. I have a fork of 3.5.3 with minimal changes to work headless with LWJGL already. If there's desire to switch upstream I can open an issue and work on a PR for here or your branch. Mainly a need to push things down into the Surface implementations. And find a way to execute tasks on the main thread.

Should be fixed with the JOGL 2.4 RC that's included with 4.0a1.
