Hi. I'd like to make two proposals regarding JNI that I'd like to see in java policy. 1) Common JNI library directory: I'd like to see all JNI modules, i.e., the C libraries that implement the native Java methods, placed in /usr/lib/jni/. I believe it would be nice to centralise their location the same way that Java classes are all placed in jars in /usr/share/java/. 2) I'd like to see policy require that all Java virtual machines include /usr/lib/jni/ in their default library search path. Currently the library search path has to be specified on the command-line with - -Djava.library.path=/usr/lib/jni or whatever. But to actually use the JNI classes, you already need to explicitly include /usr/share/java/foo.jar in your classpath and the Java classes then specify which C library to open, so I see no need to have to explicitly specify the C library search path as well. I realise (2) is a tall order for JVM maintainers, but I believe it will make things somewhat more sane in the long run for apps or libraries that use JNI classes. Consider writing a Java program that uses library X which uses library Y which has JNI methods; then (in the current setup) the startup script for this Java program has to keep track of where library Y places its C library and must add a corresponding -Djava.library.path= argument to its java invocation. I'd like to get rid of that all together and just require the startup script to add libX.jar and libY.jar to the classpath, end of story. Presumably (2) could (if desired) be implemented in a wrapper script, similar to what gij-wrapper-3.2 provides at the moment, and this wrapper script is then what's actually offered as the /usr/bin/java alternative. Note that this wrapper script would need to see if any -Djava.library.path arguments are *already* being passed and if so then simply augment that list with /usr/lib/jni. Thoughts?
