This JVM error also seems to occur for me when i replace older versions of apps with newer ones...be wary of this method as you should prompt yourselves to uninstall the app first with a soft system reboot and then install the new version...I encountered this problem today after installing a newer version of
Empower HTML reader and it took me roughly 7 hard reboot cycles and a lot of patience before i got it to hook on and stay on...
Tip:
When you have this string of JVM errors whether it be 523 or any other, try turning off the radio for a shot amt of time until the system finishes loading everything after the security check.
Hope this helps.
