Correct. javax.swing support in libgcj/GNU Classpath is still 
incomplete, however it is being actively worked on. If you'd like to 
contribute by implementing some of the missing methods/functionality, 
we'd be very grateful!

Note that if you are planning to use CNI to call Java code from C++, you 
should compile your C++ code with a version of g++ that matches your 
version of gcj. ie: trying to call Java code compiled with gcj 3.5 from 
c++ code compiled with apple gcc 3.3 will not work.
