I am observing a strange behavior on some of my Windows machines. I have a Server application that uses Java JRE 1.6u26 (Oracle) which is bundled within it. Sometimes a machine reboot causes the rt.jar file within the JRE to be deleted.

As a result, this corrupts the JVM and causes to the Server application to not startup (after the reboot).

This is really sporadic and pretty hard to reproduce.

Any help on how I could trace the issue?

Thanks,

Shreyas

Sounds like hard drives failing and checkdisk removing broken files as a result. – Philipp Reichart Sep 22 '11 at 22:11

This is a "system management" issue, not a programming issue. – Stephen C Sep 23 '11 at 2:38

@Philipp Reichart - but you'd expect that to only happen on one machine ... not "some of my Windows machines". I'd be more inclined to point the finger at a malignant virus checker. – Stephen C Sep 23 '11 at 2:40
@StephenC +1 for the virus checker. My case would probably only happen on multiple machines if there are many machines and someone bought a broken production batch of hard drives for all of them. – Philipp Reichart Sep 23 '11 at 8:13
@Philipp Reichart - but what is the chance that all of multiple disks failing on the blocks within rt.jar? And (apparently) nothing else? – Stephen C Sep 23 '11 at 12:30
