Debian package: Allow installation with openjdk-8-jre and with headless JREs

[sathieu]

On Debian 9 (jessie), installing Jolokia when openjdk-8-jre (the default
JRE) is installed will pull openjdk-11-jre (or worst, oracle-java6-jre when
available). The reason being openjdk-8-jre has Provides: java2-runtime, but no
Provides: java-runtime (this is a bug on Debian's side that won't be
solved because Jessie is now LTS).

Also, Jolokia works with headless JRE. Adding those as alternative
depends.

I don't understand why the ci is failing...

[sathieu]

@rhuss Please review and help me with the failing CI (which should not be affected by this change).

[rhuss]

Thanks looks good to me. The test looks like a flake that should have been fixed already. Let's merge this PR as the failure is clearly not related to the change here.

[sathieu]

Thanks @rhuss. Is there any release planned soon? Latest was one year ago ⌚, no hurry of course 🏃 ...

[rhuss]

yes, I plan a release soon. Need to wrap up some threads but this should be within the next month or so

[sathieu]

Great!
