That sounds much more likely.  OpenJDK already looks in the correct libdir,
and adding "%{_libdir}/jni" would be a simple change.

The code that sets the path is here in java_md.c:

	sprintf(new_runpath, "LD_LIBRARY_PATH="
		"%s:"
		"%s/lib/%s:"
		"%s/../lib/%s",
		jvmpath,
#ifdef DUAL_MODE
		jrepath, ((wanted==64)?BIG_ARCH:SMALL_ARCH),
		jrepath, ((wanted==64)?BIG_ARCH:SMALL_ARCH)
#else
		jrepath, arch,
		jrepath, arch
#endif
		);
