[fedora-java] Proposal to deprecate _prefer_jre

[Mikolaj Izdebski]

_prefer_jre is environmental variable, which once set to true causes
javapackages-tools to prefer JRE over JDK when choosing JVM to use.

_prefer_jre was most useful in multi-JVM scenario. For example when
there was JDK 1.5 and JRE 1.7 installed, javapackages-tools would choose
JDK 1.5 by default. Setting _prefer_jre=true would allow more recent JRE
1.7 to be used instead.

Currently in Fedora there is only one Java implementation. Moreover,
with Java 9 distinction between JDK and JRE becomes less clear.
Therefore I propose to deprecate _prefer_jre environmental variable and
remove it in a future release of javapackages-tools, in a year or so.

Any objections or comments?
