Looking for a contract developer. JOGL, macOS/Windows

I'm looking for a contract developer for a few weeks to update a legacy app to function on newer versions of macOS.

We used the NASA WorldWind Java engine.

Please contact me if you or someone you know is interested and available.

Hello

By the way, there is a spelling mistake in the instructions, it's written "avoided by by".

Please can you elaborate about the particular concerns on newer versions of OS X and JOGL?
