I can see the logic here, but doesn't it amount to a redesign of CNI?
This:
jobjectArray
java::io::File::performList (java::io::FilenameFilter *filter, 
			 java::io::FileFilter *fileFilter, 
			 java::lang::Class *result_type)
would become this:
jobjectArray
java::io::File::performList (JavaPointer<java::io::FilenameFilter> filter, 
			 JavaPointer<java::io::FileFilter> fileFilter, 
			 JavaPointer<java::lang::Class> result_type)
Hmm. I guess it doesn't look too awful.
Andrew.
