As Blackbird says, use the latest version of LW (the link to the Pro Beta is on the bottom of your Pro page).

Mac's Runtime version of Java' Virtual Machine (MRJ VM) that runs on OS 9 is confusingly labeled. It's the "MRJ 2.2.5" located in your utilities folder. Here's the link for more info http://docs.info.apple.com/article.html?artnum=75097

So, if you already have it,you just need to download the LW installer with no VM.

[btw--spearson (Soren) posts about OS 9 most--watch especially for his posts]
