--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- libjavamath uses nativeexeclib_LTLIBRARIES = libjavamath.la and inside classpath nativeexeclibdir='${toolexeclibdir}/gcj-'`cat ${srcdir}/../../gcc/BASE-VER`-`awk -F: '/^[[^#]].*:/ { print $1 }' ${srcdir}/../libtool-version` (eh) thus not multilib aware. 4.8 put the gcj-4.8 dir in /usr/lib64/, thus not aware of version-specific dirs and it contained classmap.db libjavamath.la libjavamath.so libjvm.la libjvm.so Why wasn't that "version-specific" enough? (it has the -sover suffix?) If it wasn't enough the whole stuff should be below /usr/lib64/gcc/x86_64-suse-linux/4.9/ which means both path variants used by 4.9 currently are bogus. I think given the current state of libjava maintainance reverting the change is the best.
