I just had this error message from one of my users. (IE8, Java 1.6.20 ). It is from an applet which receives instructions from Javascript and executes certain processes on the client.
RangeError
java.lang.RuntimeException: ERROR: Failed to recover corrupt cache entry

Any iddeas what could be causing this?
