I am not saying that they shouldn't be below /usr/lib, but I think that 
they shouldn't be right in /usr/lib. For example in /usr/lib/jni could
be right. I just have reread the FHS it indeed isn't completly certain
that it is right, since it says that 

  "Applications may use a single subdirectory under /usr/lib. If an
  application uses a subdirectory, all architecture-dependent data
  exclusively used by the application must be placed within that
  subdirectory."

So if there is already a directory holding java related architecture
dependent files, it should be used instead. Seems like there are already 
some directories for java in /usr/lib, I don't know exactly what is
their use. They are owned by jpackage-utils and are:

/usr/lib/java        /usr/lib/java-1.4.1  /usr/lib/java-1.6.0
/usr/lib/java-1.3.1  /usr/lib/java-1.4.2  /usr/lib/java-ext
/usr/lib/java-1.4.0  /usr/lib/java-1.5.0

Maybe one of these directory is searched for for jni libraries. In that
case I think it should be used instead of /usr/lib.
