Installing OpenJDK9-jdk fails on fresh 16.04

[hasno]

Tried to install openjdk-9-jdk using apt-get on a fresh Ubuntu 16.04 64bits installation, but it gave me an error:

dpkg: error processing archive /var/cache/apt/archives/openjdk-9-jdk_9~b114-0ubuntu1_amd64.deb (--unpack):
 trying to overwrite '/usr/lib/jvm/java-9-openjdk-amd64/include/linux/jawt_md.h', which is also in package openjdk-9-jdk-headless:amd64 9~b114-0ubuntu1

This also happened to other users, see http://askubuntu.com/questions/769467/can-not-install-openjdk-9-jdk-because-it-tries-to-overwrite-file-aready-includ
