Now with the right address. Original was CCed to pr already so this is not.

Subject: News item: Generation 1 deprecation
Date: Monday 23 February 2009
From: Petteri Räty <petsku@petteriraty.eu>
To: gentoo-dev@lists.gentoo.org

We are getting near to having all generation 1 Java ebuilds gone from
the main tree so we made a news item in order to instruct how to remove
left over things if wanted (nothing breaks if you don't).

Last bugs to fix before we commit the new java-config-wrapper and the
news item:
http://bugs.gentoo.org/showdependencytree.cgi?id=176781&hide_resolved=1

The news item will go in at the same time with the new
java-config-wrapper that is adjusted to check for deprecated generation
1 files.

Regards,
Petteri

Title: Generation 1 Java Setup Deprecated
Author: Petteri Räty <betelgeuse@gentoo.org>
Content-Type: text/plain
Posted: yyyy-mm-dd
Revision: 1
News-Item-Format: 1
Display-If-Installed: >=dev-java/java-config-wrapper-0.16

For a long time the Java team required a 1.4 JDK to be
installed in order for old java ebuilds to work. All these
ebuilds are now gone from the main tree so the requirement
to have a 1.4 JDK installed has been lifted.

In order to remove things left over by the generation 1
setup please run java-check-environment and follow the
instructions.

If you want to remove 1.4 JDKs, you should use emerge --depclean.
Depending on what you have installed you might not need a
1.4 JDK any more. To see if you still need a 1.4 JDK use:

emerge -av --depclean virtual/jdk:1.4

If don't need virtual/jdk:1.4 any more then you can remove the
individual JDKs. First get the list of installed JDKs with
eselect and then remove with depclean, for example:

eselect java-vm list
emerge -av --depclean sun-jdk:1.4

I got 

For more information, see the MASKED PACKAGES section in the emerge

(dependency required by "dev-java/tomcat-servlet-api-5.5.27" [installed])
(dependency required by "dev-util/eclipse-sdk-3.4-r2" [installed])
(dependency required by "@world" [argument])

and after looking at the tomcat-servlet-api ebuild I finally found that 
setting a java5 use flag and re-emerging the ebuild would be required, et 
voila...


It's really great that the Java team managed to convert all packages, but I do 
not call the above procedure user friendly. ;)

Did you read the email? The the new java-check-environment is not in yet
and doesn't the news item say that 1.4 might still be needed?

We don't want to turn on java5 use flag by default because of
http://bugs.gentoo.org/show_bug.cgi?id=161622

Any way in your case the user is expected to decide that he still needs
1.4 and leave it installed.

Well nothing breaks if you don't do anything. Guess that should be
reflected better in the news item. You will just have extra stuff in
your $PATH most likely etc.

FYI, the item was finally posted yesterday after everything else needed
was done, so gen1 is gone now.
