Mike,

Todd mentioned earlier that JLink 3.0.2 is exactly the same as JLink 
3.0.1 with the exception of one fix to deal with the bug introduced by 
10.3.8 update.  The version that users can download IS JLink 3.0.2.

You can't compare Mathematica 5.0 with 5.1.  Mathematica 5.0.1 came with 
JLink 2.1.1 (September 30).  When I read your first post, I assumed you 
were talking about InstallJava[] hanging (and I bet Todd did as well). 
I re-read the post and you actually didn't indicate what's wrong.

The error message: "InstallJava::uifail:The separate Java user-interface 
link could not be established" and "InstallJava::fail: A link to the 
Java runtime could not be established" are not related to what was 
change in JLink 3.0.2.

Take a look at this thread, as it might be related to your issue.

As far as the release notes, it must be a simple typo someone forgot to 
update.  I'll forward that info to the appropriate people.
