A DESCRIPTION OF THE REQUEST :
The jre/jdk rpms do not support the "alternatives" command which is used in Fedora and other distros.

JUSTIFICATION :
Individual users can choose to use jre/jdk instead of the default java by changing PATH, MANPATH, and probably some other environment variables, but the jre rpm does not support a global choice by the system administrator using the alternatives command to make the links in /etc/alternatives point to the /usr/java/default/ files.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The rpm scripts should ensure that one of the alternatives for java available to the system administrator is the jre/jdk. And incidentally, for this to work properly, the man pages need to be gzipped.
ACTUAL -
No alternatives commands are executed.
