In that case the reference to the Mac OS 8 & 9 preference folder location should probably be removed & a note placed explaining this doesn't apply to their versions. You'd be surprised how many pre-OSX users there still are out there. Of course, add to that those who are still using Mac 10.1->3, & are thus also not able to use the new feature, as the last version 10.3 users can use is LW 4.12.16, & for OSX 10.1 is LW 4.8.1. Altogether that's a lot of mac users in the gnutella community. Only those who use OSX 10.4 or higher can use the hostiles list. Should probably be noted on your first or second post in this thread.

Java 1.5 was only introduced in OSX 10.4. And Mac has not released a Java 1.6 at this stage. Perhaps with the new OSX 10.5 being or soonish released, will mac release a Java 1.6.
