Any chance it could be a bug with jogl?

No chance at all, these methods are used in several engines and frameworks based on JOGL 2 (LibGDX, the abandoned JOGL backend of JMonkeyEngine 3, the legacy version of Ardor3D, etc).

I advise you to look at this example written by Xerxes:
https://jogamp.org/cgit/jogl-demos.git/tree/src/demos/es2/RawGL2ES2demo.java?id=HEAD

Look at the line n°411.
