Re: [ jEdit-devel ] should jEdit 5.1 depend on Java 6 or 7?

[Alan E. <ala...@gm...>]

One reason is: I think 5.1 is very close to being released, and we just
have a few more patches to accept and we can bump trunk to the next version.

Another reason is: I think it is beneficial to work on 2 different java
versions, and the mac users will probably agree.

Another reason is: while users all agree, the developers do not.
