[fedora-java] jpackage-utils on FC4 (x86_64 issue mainly)

[Carwyn Edwards <carwyn@xxxxxxxxxx>]

Why does macros.jpackage in jpackage-utils-1.6.3 on FC4 still use 
%{_prefix}/lib/jvm references while jpackage.org macros.jpackage in 
jpackage-utils-1.6.4 (1.6.3 too allegedly) uses %{_libdir}/jvm?

The really confusing part is that FC4 seems to have picked up 
jpackage-utils up _after_ the change was made in the jpackage.org 
version!? (around 1.6.3 when the chagelog lists the change at 1.6.2).

The end result is that the FC4 x86_64 gcj-compat package is in 
/usr/lib/jvm rather than /usr/lib64/jvm. The unfortunate thing though is 
that the link part of the alternative slaves also end up pointing at 
/usr/lib/jvm.

I hit this while trying to finish off the Jpackage jdk cleanups I 
started a while back. Updating to jpackage-utils 1.6.4 from jpackage.org 
then trying to install a x86_64 Jdk built against it fails if the 
gcj-compat package is installed as the alternatives link names are 
different:

  1:java-1.5.0-sun         ########################################### 
[ 14%]
link /usr/lib/jvm-exports/jre incorrect for slave jre_exports 
(/usr/lib64/jvm-exports/jre jre_exports)

The culprit being:

--slave /usr/lib64/jvm-exports/jre  jre_exports  
/usr/lib64/jvm-exports/jre-1.5.0-sun

.. which of course conflicts with the link name already installed 
against "jre_exports" for gcj-compat which lists jre_exports as being a 
link from /usr/lib/jvm-exports/jre.

The workaround is to stick with the jpackage-utils in FC4 I guess. Still 
it's a good example of how mixing JPackage and FC4 can cause problems.
