By "renderer" I meant a GLEventListener.
There is only one process, but this portion of code below can be called by different (Java) threads: there is one different offscreen drawing per thread. The errors I observed are always thrown in the init() method of the GLEventListener.

AbstractGraphicsDevice device = GLProfile.getDefaultDevice();

GLDrawableFactory factory = GLDrawableFactory.getDesktopFactory();
GLProfile profile = GLProfile.getGL2GL3(device);
GLCapabilities capabilities = new GLCapabilities(profile);
capabilities.setBackgroundOpaque(false);
capabilities.setOnscreen(false);
capabilities.setFBO(true);
                                       
GLOffscreenAutoDrawable drawable = factory.createOffscreenAutoDrawable(device, capabilities, null, width, height);
                       
mRenderer = new MyGLEventListener(); // implementation of GLEventListener
drawable.addGLEventListener(mRenderer);
drawable.display();


Does it look incorrect ?
