Subject: Proposal to deprecate _prefer_jre
_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?
+1 . It's not widely used and is yet another reason for unpredictability.
I don't understand this effort.
With https://bugzilla.redhat.com/show_bug.cgi?id=1098508 in mind - why to abandon it?
I'm not exactly against this proposal, but I still have an feeling that there is underlying issue in java packages or in jtools.
The correct approach, if jre + sdk separation will be kept, should be:
only jre installed - use jre
sdk installed (jre installed as dependence) :
- application requires jre - use jre
- application rewires devel, use jdk
Now - jdk9 ... is different. Maybe something can be done better so jtools nor java apps suffer by above logic.
