Any chances to have openjdk11-jre and openjdk12-jre?

 By using Oracle-blessed way to package applications with JRE: by using
jdeps and jlink utilities. jdeps extract all modules needed by this
software (set of JARs) and jlink creates minimal directory which
contains everything is needed [1]. It is not general-purpose JRE for
system-wide installation, it is JRE tailored for this specific software,
but it is even better for my use case, as it is rather small (41MB!).

 I'm adding options to UniFi port right now to be able to produce
self-sufficient UniFi package (turned off by default) with JDK11 or
JDK12 (on user choice), which brings it own minimal JRE and doesn't need
system-wide one, to use on appliance-like (read: NanoBSD-generated)
devices. I'll post PR later.
