This is something specific to the Sun JVM.  I have heard of this before
but I can't remember how one fixes it.  It's something to do with
java.library.path, IIRC.

Sort of.  What we ship with Fedora is both the bytecode *and*
corresponding native shared object files.  This allows gij to use
the .sos and other JREs to use the bytecode.

There is much confusion surrounding the best way to install Sun's
JVM/JDK on Fedora.  IMHO, using the JPackage setup to allow your JREs to
be alternatives-managed is the best way to go.  There are other ways, of
course, including installing the Sun binary blobs into /opt or
elsewhere.  This has been covered many times on the list and Tim points
out one of the many sites regarding this.
