openhab2 incorrectly does not depend on java

[RREE]

I could install openhab2 on a raspian (Jessie) system without previous installation of any java runtime.

I created /etc/apt/sources.list.d/openhab2.list with the following contents:
deb https://dl.bintray.com/openhab/apt-repo2 stable main
$ aptitude update
$ aptitude install openhab2
worked without any mention of java.

Only when looking into journalctl I saw the following lines:
Aug 28 21:15:51 z3 start.sh[524]: /usr/share/openhab2/runtime/bin/setenv: line 176: type: java: not found
Aug 28 21:15:51 z3 start.sh[524]: /usr/share/openhab2/runtime/bin/setenv: line 179: die: command not found

Could you please report this at https://github.com/openhab/openhab-linuxpkg/issues as this is the repo that deals with Linux packaging? Thanks!

Please note that for the later versions of openHAB, apt will now recommend Java.

We cannot depend on it via a package manager as there are many different ways of including it. For example, via manual extraction, or by installing either or multiples of Zulu/Oracle/open JDK.
