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

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.
