Solaris Nevada (build 92) ships with most of the useful java programs linked to /usr/bin/<prog>. Unfortunately the man pages are still squirreled away in /usr/jdk/<java version>/man. This is inconsistent and results in an installation where java is in the default path but a "man java" results in "No manual entry for java.".
Just as the java binaries are linked into /usr/bin so too should the man pages be linked to /usr/share/man.
