MIke: I unjar'd my app.jar yesterday and did `file Application.class` and it returned version 49 - so it looked normal. I am running now though. On Eclipse's 'Installed JREs' preference pane, I checked "JVM 1.6.0 (MacOS X Default)." I had previously selected 1.5 there. The compliance setting has always been at 1.5. But my next build ran.
The weird thing is that I haven't changed any JVM or java settings in recent weeks. I have no idea why that change effected anything. I hadn't changed any java settings recently. And I have no idea which classes I produced were wrongly versioned since everything I looked at seemed correct.
