I am not sure why, as JRE 1.6.0 was released a while back.

In what R version?

It probably should be /usr/java/jre1.6.0/jre: it certainly is in the
released version of 1.6.0.
Did you perchance set JAVA_HOME incorrectly? If you add Sun Java 1.x.y to
a Fedora Core system, you need to add a java-xxx-sun-compat RPM (from
jpackage.org), and I don't see why 'Redhat Linux' should be any different.
OTOH, on my system setting JAVA_HOME=/usr/java/jre1.6.0 seems to actually
work, although Simon Urbanek tells me it is not as intended (and not what
java will tell you its home is).
