I would rather say : Upgrade your java to the latest release (1.4.2.22). That will also be the first thing HP support will ask you to do.

I have also had this type of java errors in the past (with 1.4.2.07) : They occured at random times, sometimes a few months without, sometimes twice a week.
After uprading the java version, I have never seen them again.
