I have a web app that uses a Java Applet for various functions like finding network devices through multicast, as well as combining XML and a xsl-fo template for printing.
Recently most of my users (an intranet web app) upgraded to Java 7. Ever since a small proportion of my users (5-10%) are having random crashes in IE with the exception code being
Exception code: 0xc0000005
Which I believe is an EXCEPTION_ACCESS_VIOLATION.
The fun part is that the 5-10% all seem to be in a few offices where 50% of the users get it and 50% don't.
I have had the users run SFC /scannow to determine if there are any corrupt system file's and some users are fixed after that, but most aren't.
