Well, I'm not the Java team, but I've run into similar problems.
The only library I've ever had to explicitly load from Java has been
the one that contains my native methods. However, I have also had to
load some non-standard ones that my native methods depend on. All I have
to do is link those libraries with my c-code using the -R option. (in order
to save the path of the linked library)

These routines aren't in those libraries. They're a part of the java
executible.
I ran into that problem because I'm using C++ and Java. If that's the case
for you too, be sure you're using 'extern "C" { }' correctly.
Hope this helps.
