True; I overlooked the fact that it was the swt-java -> swt-jni
dependency.  That said, javahelper never supported those!  Those are
from the same source and usually the Java package needs a very strict
dependency on the JNI dependency.

*In the particular case* - SWT is a bit special here, because it builds
a mandatory JNI (libswt-gtk-3-jni) and several "optional" extensions
(e.g. libswt-cairo-gtk-3-jni).  I suspect that gnukhata need to declare
a dependency on libswt-cairo-gtk-3-jni if it needs that particular
extension.
 * Admittedly, libswt-gtk-3-java could do with a Suggests/Recommends on
   its "optional" JNI packages.
