SoyLatte/OpenJDK and Apple's Java on Leopard both load dylib and
jnilibs.

I'm not sure what the problem with SoyLatte is, but I do know why you
had a problem using the Java SE 6 supplied by Apple.
The problem is that the process that is loading the library has an
architecture mis-match. Java SE 6 as provided by Apple is Intel 64-bit
only:
% file /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/
Libraries/libj2pcsc.jnilib
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Libraries/
libj2pcsc.jnilib: Mach-O 64-bit dynamically linked shared library x86_64
but the library it's trying to load is only PPC/Intel 32-bit:
% file /System/Library/Frameworks/PCSC.framework/PCSC
/System/Library/Frameworks/PCSC.framework/PCSC: Mach-O universal
binary with 2 architectures
/System/Library/Frameworks/PCSC.framework/PCSC (for architecture
i386): Mach-O dynamically linked shared library i386
/System/Library/Frameworks/PCSC.framework/PCSC (for architecture
ppc7400): Mach-O dynamically linked shared library ppc
Please file a bug at http://bugreporter.apple.com with a code example
of how you can reproduce this problem, along with any suggestions on
the best way to resolve it.
Hope this helps explain what is going on,
