Driver tries to load library by name, not by path. The only thing you have
to do is to specify directory with jaybird.dll in the java.library.path
system property. By default, java.library.path equals to the %PATH%, but you
can do something like this:

java -Djava.library.path=<path_to_jaybird.dll>;%PATH% -classpath ...
com.myapp.Main ...

And, note, fbembed.dll is loaded from the PATH (not java.library.path).

In theory driver could load library from the place specified in properties
(and I also started to work on this solution), but there are some internal
issues that must be solved first, so that solution will not appear in the
nearest future.
