OK.. dusting off the java cobb webs.... So JavaEmbedding is for  
native Carbon/Cocoa (10.3.9/ppc) that need to instantiate a Java VM  
_within_ the application itself... like a web browser would do if it  
needed to display a Java Applet in a web page. This is NOT what VTK  
with java Wrappings are doing.

    What the VTK/Java combo is doing is launching a native java  
program. Then within that java program the VTK JNI libraries are used  
to access VTK functionality. Do you understand the difference?

    So I stand by my earlier, although cryptic post, and say that the  
VTK java Wrappings need to link against
"-framework JavaVM" instead of the JavaEmbedding Framework.

David, can you make the change please and lets see what the  
dashboards come back with. Also is this a CMake change or a VTK Change?

Thanks to everyone for sticking with this problem.
