I’ve found that when I use this method:
Graphics2D.drawImage(BufferedImage image, AffineTransform trans, null); on Mac OSX, when the image has translucency, the image looks like it’s turned opaque with a black background.
Linux and Windows do it fine. Is there something I don’t know about with OSX? Is there a bug already filed for this? If so, how can I find it? I never seem be able to find anything I want in the bug list
When you find a bug on OSX - ALWAYS file a report. You can’t find out if it is already reported, and Apple uses the number of reports for the same issue to prioritize their work.
Bugs in the Apple JRE implementation are not listed on Suns bug database, unless they are also bugs in the core JRE that Apple gets from Sun.
I can’t. I have to submit a System Report along with the bug which requires that I grab a file off of my Mac. Only problem… I don’t have a mac. It’s rare that I get to test on one. So since I can’t fill in that required field, it won’t take my bug report.
You can make a simple test for me to run on my mac. Then you could get my system report 
Yeah, make a test case. Then post your testing request to a mac list. Apple has a game-dev list and a java-dev list explaining that you can’t file the bug because of that required field. I’m sure you will get a few people that will help you out. Some may even file bug reports of their own on your behalf.
