I believe the problem only occurs if you ran an upgrade to Panther. The Java package didn't update on its own, but there are ways to do it yourself. I had the problem and fixed it by using the script provided in the .sit file posted on this site: http://jqkserv.net/xplanehelp/viewar...jsp?kbid=10087

When I got to the part where you're supposed to type ./fixit.sh and then hit the enter key, I got an error saying that Java.pkg was a folder (meaning it couldn't remove it with the rm command). I went to my /Library/Receipts/ folder and deleted the Java.pkg file manually, then continued with the rest of the instructions provided in the .sit file. When I was done, I reinstalled LimeWire and I was good to go =)
