After installing the latest security updates, davmail stopped working.
I looked into it and found out, that it required the file '/usr/lib/jvm/java-11-openjdk-amd64/lib/libawt_xawt.so' which was now missing even tho it's supposed to be installed as part of the openjdk-11-jre-headless package, which is installed as one of davmail's dependencies.

I asked for help in the #debian IRC channel, and we came to the conclusion that the file has been moved to the openjdk-11-jre package.
The package content list do not reflect those changes yet. Please adjust the list of the package contents for openjdk-11-jre-headless and openjdk-11-jre in Buster to avoid further confusion.

PS: It may also be a good idea to change the dependency from davmail from openjdk-11-jre-headless to openjdk-11-jre as well or add it as a recommended or at least suggested package.

Control: clone -1 -2
Control: reassign -2 src:davmail

Right, I'm curious which component needs libawt_xawt.so.  The package already
lists libswt-gtk2-4-jni, libswt-cairo-gtk-4-jni, libopenjfx-java as suggestions,
so maybe these should be upgraded to recommendations as well?  Or is it possible
to split out the UI components into a separate package?

Control: severity -1 serious


   * Move libawt_xawt.so, libjawt.so into the jre package. Closes: #908058.

Such changes should not happen in an update to stable.

Well, if you are forced to use 2FA with Office365 (like I am), davmail
will open a window that asks you for the verification sms, otp code or
similar.
I do not have libswt-gtk2-4-jni or libswt-cairo-gtk-4-jni installed, so
those are not required for that. Therefore I do not think that those
should be promoted to "recommended".
When I try to remove libopenjfx-java however, it tells me that it's
going to remove the packages davmail and libopenjfx-jni as well, so I
guess libopenjfx-java already is a hard requirement somewhere in
davmail's dependency tree.
Granted, if you use 2FA and need to have an X-Server running on your
server because of that, it's not exactly headless anymore... I still
think making openjdk-11-jre a recommended or at least a suggested
dependency would be a good idea because of it.
Not sure how much effort it would be to split davmail like that or if it
would be a good idea.
