I have MacOS 8.6 and a java SDK install started type 2 errors with limewire.
I use a apple script to remove JDKToolsCLasses.zip and MRJSDKClasses.zip from
the folder MRJ Libraries in the system folder before starting limewire.

on run

tell application "Finder"
activate
if (count items in folder "MRJClasses" of folder "MRJ Libraries" of folder "Extensions" of folder "System Folder" of startup disk) > 2 then
select {file "JDKToolsClasses.zip" of folder "MRJClasses" of folder "MRJ Libraries" of folder "Extensions" of folder "System Folder" of startup disk, file "MRJSDKClasses.zip" of folder "MRJClasses" of folder "MRJ Libraries" of folder "Extensions" of folder "System Folder" of startup disk}
move selection to folder "DownLoader" of startup disk
select file "LimeWire" of folder "LimeWire" of folder "Applications" of startup disk
open selection
else
select {file "JDKToolsClasses.zip" of folder "DownLoader" of startup disk, file "MRJSDKClasses.zip" of folder "DownLoader" of startup disk}
move selection to folder "MRJClasses" of folder "MRJ Libraries" of folder "Extensions" of folder "System Folder" of startup disk
end if
end tell
end run
