The Requires are the main part of this package – as it brings all the 
stuff together to make the complete 'JDK'.

Only the symlink, or rather the libjvm.so library with all the dependencies?

The library is a part of the JRE. I guess we could move the 
%{_libdir}/jvm/java symlink to icedtea8-jre, but it still needs to pull 
whole JRE (that is still less than JDK).

The symlink is there to allow multiple JDK/JRE versions installed (Java 
world is crazy and one may need that) – the symlink points to the 
current default one.
