[fedora-java] Saner Java packaging

[Alexander Kurtakov]

Time to bring GCJ support discussion back.
We should find a way to not install java-1.5.0-gcj on every users computers. 
There are packages that do not work with it and it's plain wrong to install it 
as a dependency of this packages which are explicitly requiring java 1.6.0.
Possible solutions:
 * Solution 1 - someone who cares for the gcj stack finds a way to not require 
java-1.5.0-gcj when there are gcj bits in the package so we do not force gcj 
installation on every user.
 * Solution 2 - drop gcj support from packages, interested maintainers can add 
gcj bits as a subpackage which requires java-1.5.0-gcj. I think that this is 
what Debian is doing.

I will also propose changing Java Packaging Guidelines to not require or 
recommend the addition of gcj support bits.

Any comments?
