Hi, I think we have reached a point in the release cycle when it becomes difficult to predict the outcome of implementing 1. We simply can't foresee all consequences. We know it works for dicomscope but what about all the other packages that depend on jarwrapper? Most people depend on jarwrapper because the Java policy states: "If the package installs a jar (or a symlink to a jar) as an executable the package must have an absolute dependency on *jarwrapper or an equivalent package*" Now they have certain expectations for jarwrapper and since we haven't seen any complaints except this bug report so far, we should assume that jarwrapper works in general. I suggest the following: 1. Clone this bug report, retitle to "Make jexec the default binfmts (before jarwrapper)" and lower the severity to important. This change should be discussed on debian-java anyway but it is not RC. 2. Fix this bug by applying the attached patch and removing the java.library.path from jarwrapper. As Emmanuel already said before, the openjdk packages can find the correct multiarch path and jarwrapper should let those packages handle it. 3. Please note that dicomscope could "depend on jarwrapper or an equivalent package". You could also write your own wrapper script or use java-wrappers instead. 4. I think Mathieu is right and dicomscope should install the native libraries into specific *-jni packages. The Java policy should be changed to say "must be shipped in a separate package" instead of "should". In any case dicomscope:amd64 and dicomscope:i386 are currently not co-installable, so the whole discussion about the java -d32|64 hack is rather academic at the moment. On a side note: jarwrapper exports LD_LIBRARY_PATH=/usr/lib/jni. Was this ever useful because -Djava.library.path is still used? Regards, Markus
