Well it might be a combination of a couple of things Ive realized in my OSX Preferences I have Energy Saver/Display Sleep and Computer Sleep set to 15 minutes, so I guess that after 15 minutes the Display Sleep will make the screen go black even if progress bar updating because no user has touched keyboard/mouse but computer sleep doesnt kick in because its detect the application is active. But then once Display Sleep is blank that tells AppNap it can pause any application and it does. Clicking on the Properties of the Application and preventing AppNap seems to ensure process continues processing even after screen gone black Is my summary correct ? Paul
Re: Nimbus color differences between JDK versions
Hi, my email may have been premature. I just learned that we are mixing Nimbus and Quaqua (using a modified QuaquaTreeUI in our UI which is derived from Nimbus) and maybe the color difference comes from a behavioral change in one of the L&Fs resulting in the color mismatch. I will report back after some more investigation.

Re: Java 7 application halting OSX when left unatteended
Hello, Paul. Is this issue specific to Mavericks or it is also reproducible on 10.8? Could you please provide some test case to reproduce? Or any Swing based application with some background task would work? Thank you. With best regards.

Java 7 application halting OSX when left unatteended
My (java 7 based) Gui application processes digital music files, and is designed so it can be left unattended. I have noticed that if I leave it running overnight on my OSX Mavericks computer that it stops shortly after I leave it, only continuing when I touch the keyboard in the morning. How can I prevent this, I do not have the same problem running the application on a Windows 8 machine. paul
