Package: openjdk-9-source Version: 9~b181-4 The file src.zip is placed into the directory /usr/lib/jvm/openjdk-9/lib, but should be placed into the directory /usr/lib/jvm/openjdk-9. Or, the symlink /usr/lib/jvm/java-9-openjdk-amd64/src.zip should be changed to point to the correct file (currently, it is dangling).
