This is great news. I kept an eye over the years on Haiku but last executed it in a VM a few years ago.
I didn’t know you have OpenJDK running! Is it only JDK 8 or even newer JDK 10 (or 11)?
I am involved with the Apache NetBeans (and CoolBeans) IDE. How can I help?
It would be interesting to see the latest version running on Haiku OS.
