Bug#901045: libopenjpa-java: fails to upgrade from 'stretch' - trying to overwrite /usr/share/doc/libopenjpa-java/examples/image-gallery/pom.xml.gz

[Andreas Beckmann]

Package: libopenjpa-java
Version: 2.4.2-4
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts

Hi,

during a test with piuparts I noticed your package fails to upgrade from
'stretch'.
It installed fine in 'stretch', then the upgrade to 'buster' fails
because it tries to overwrite other packages files without declaring a
Breaks+Replaces relation.

See policy 7.6 at
https://www.debian.org/doc/debian-policy/#overwriting-files-and-replacing-packages-replaces

>From the attached log (scroll to the bottom...):

  Selecting previously unselected package libopenjpa-java.
  Preparing to unpack .../31-libopenjpa-java_2.4.2-4_all.deb ...
  Unpacking libopenjpa-java (2.4.2-4) ...
  dpkg: error processing archive /tmp/apt-dpkg-install-NFPJRg/31-libopenjpa-java_2.4.2-4_all.deb (--unpack):
   trying to overwrite '/usr/share/doc/libopenjpa-java/examples/image-gallery/pom.xml.gz', which is also in package libopenjpa-java-doc 2.4.0-4
  Errors were encountered while processing:

cheers,
