Apple Outsider has a good piece on Java on Mac OS X. If you haven’t heard, Apple has announced that the current version of Java has been deprecated. This means that Apple is not going to keep creating their own Java VM for OS X. Apple is relying on Oracle/Sun to make a VM for OS X now. Steve Jobs himself reportedly emailed a developer and said “Sun (now Oracle) supplies Java for all other platforms. They have their own release schedules, which are almost always different than ours, so the Java we ship is always a version behind. This may not be the best way to do it.”
The only Java-based astronomical software that came to mind was Leopard/Spot which is being retired in favor of what I believe is a web-based archive. Though in my postdoc days, I recall a GUI for a data reduction pipeline that was written in Java. (My only other recent encounter with something written in Java has a connection to astronomy is tenuous at best.)
However, I’ve been out of the astronomy game for a while, so how do you suppose the possible end of Java on the Mac will affect scientific/astronomical software for the Mac? What’s out there astronomy-wise that’s Java?
