Re: [ jEdit-devel ] A note on compatibility with Java 1.5

[Dale A. <da...@gr...>]

A comment about "Mac users are limited to Java 1.5" -- it seems not all Mac
users are restricted to Java 1.5, see this link:

http://support.apple.com/kb/HT2733

and this link:

http://weblogs.java.net/blog/arungupta/archive/2008/04/java_se_6_u5_on.html

I'm not up on Macs, but it looks like you have to have a fairly new machine
and have a 64-bit Intel based Mac.
