A DESCRIPTION OF THE PROBLEM :
When the Java Control Panel is opened via the Mac OS X System Preferences Java control panel, it appears at center of the screen, then slides within about 1 second to the bottom left of screen.

REGRESSION. Last worked in version 7u51

ADDITIONAL REGRESSION INFORMATION:
Works in all earlier versions of Java. This appears to affect some other dialogs in Java applications also, but it is unclear to me what is triggering this issue so I am reporting the problem with the Java Control Panel only since it is an issue that would affect all Mac users with Java 8

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Open System Preferences on Mac OS X
2) Click on the Java preferences Icon

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Java Control Panel should appear in the centre of the screen or relative to the Java pane in the Systems Preference window.
ACTUAL -
Java Control Panel appears centre-screen and then immediately slides (animated -- taking about a second) to the bottom left of the screen.

REPRODUCIBILITY :
This bug can be reproduced always.
