Dropping Java 6 Support?
Hi All
Andy raised an interesting point recently that historically the Jena project
has only guaranteed to maintain compatibility with the 2 most recent
versions of Java. As of the recent Java 8 release this means that Java 6 is
technically now outside of the range of versions that we intend to maintain
compatibility with.
Dropping of Java 6 support is not going to happen overnight so this email is
intended to serve as advance notice that this will happen at some point in
the future and to request feedback on this. Note that it is likely that in
the short term code will remain Java 6 compatible and so a workaround after
Java 6 support is dropped will be to build from source yourself
Are there people out there who are currently reliant on Java 6 and cannot
move to Java 7/8 for whatever reason? If so what sort of timescale would
you consider reasonable for dropping Java 6 support?
Thanks for your feedback,
Rob

correction: building from source, with Java 6. I'm guessing byte code compatibility of the different versions is the same.

Rob,

I don't think that once support is dropped, you can build from source for long. If Jena project makes use of a new language feature, or library included in Java 7 or Java 8, running Jena with Java 6 will no longer be an option. True also, if any of its dependencies do the same.

Would
2.11.2 (last Java6)
then
2.12.0 (Java7).
work?

Yes I can call a vote, what I will likely propose is that we do one more
release that is Java 6 and then drop Java 6 support for subsequent releases

Rob,
Do you want to call a VOTE on this?
Then Jena 2.12.0?

This whole version thing is a bit of wobbly tower of choices from the
top down.
Fuseki2 requires Java7 because the version of Jetty (v9) it uses for the
standalone server requires Java7 (which in turn is because the version
of the servletAPI is "Servlet 3.0+").
As it is Java7, there is use of "Files" and "Path" which are quite useful.
It does not oblige the Jena libraries to be Java7.
