During SST testing of Solaris 11 update 1 nightly build from 2012-03-14 (RE) we've found that the package runtime/java/jre-6 has missing dependency on library/motif. Namely, it delivers
/usr/jdk/instances/jdk1.6.0/jre/lib/<architecture>/motif21/libmawt.so
which is linked against libXm.so.4, delivered in library/motif. However, jre-6 package doesn't declare dependency on library/motif.

# ldd /usr/jdk/instances/jdk1.6.0/jre/lib/*/motif21/libmawt.so | grep libXm
        libXm.so.4 => (file not found)
        libXm.so.4 => (file not found)
