I actually did a little research, and it seems that they are dropping QTJava altogether, but rumors are flying around stating that they are just not updating QTjava... So in theory they will include the libraries even though they may not fully function properly... Sounds like a bad rumor though.

There was also a rumour floating about that Java would be discontinued on the Mac (based on Steve Jobs' "ball and chain" comment after the iPhone launch). Although never officially rebutted by Apple, it appears to be a false rumour. Given the climate of secrecy in which Apple prefers to work, lots of rumours abound, many with little basis in fact. Will QT4J make the transition to 64-bit or not? Nobody whose talking really knows, and nobody who really knows can talk.


Log an enhancement request at http://bugreporter.apple.com to request 64-bit support for QT4J, that is the only official channel to Apple for such things (unless you're Adobe or Microsoft).

I believe that I have already clearly stated:

Oh also, I developed this to use QTJava - is it safe to assume that this is installed on every mac?

Actually, no. QTJava is only present in 32-bit processes, because Quicktime itself is only available in 32-bit processes. The QTJava API will not be carried forward to 64-bit because it is in many places a very close clone of the QT native API (int sized pointers and all).


The best advice I have going forward to 64-bit is to use JNI, and use a framework that exists in 64-bit like QTKit.


The QTJ API is not compatible with 64-bit, because the underlying QT API is not compatible with 64-bit.

Let me also be crystal clear on this point: Java has made the jump to 64-bit unlike a number of other frameworks on Mac OS X. Let's focus on technical issues here, and leave the speculation for the rumor sites.
