I had trouble with a java upgrade when moving upto the version of LW I'm running now -4.6. I think some how Java 1.3 and 1.5 got minced together... I know that this would not apply this time since I have the latest java and it's sorted now - but you're taking to a person who's watch does mysterious things unless I wear it on my wrist in a special way, lol - so I'm kinda cautious about changing things without good reason.
