Execute disable bit on an mp3 player?

[William Frick]

It is the .jar files' execute bit. I recently installed a java app and the bit needed to be set. An upgrade of the app reset it again. Good security though !

Would the .jar files need to have the execute bit set?  I would think 
that as far as the operating system is concerned, they're just data 
files for the Java interpreter/compiler.  It's the Java executable 
program that needs the X bit, and it is probably stored on your 
computer's drive, not the USB drive.
