Add a tech preview preview of the the upcoming version of Java<br>
(OpenJDK9) to Fedora 27<br>
<br>
<br>
== Detailed Description ==<br>
The current Java implementation in Fedora comes from OpenJDK.<br>
Java 9 (and OpenJDK9) are tentatively scheduled for release in<br>
2017-07-27. Fedora 27 will most likely be out just a few months after<br>
that, and is therefore positioned to receive a tech preview version of<br>
the latest OpenJDK9 candidates. This preview should be released<br>
version of Java 9, will contain new Java 9 APIs, but may not be<br>
supported by many applications directly, therefore it have to warm up<br>
as techpreview.<br>
<br>
<br>
== Scope ==<br>
The current version of OpenJDK 9 will be packaged and added to Fedora.<br>
It will be a stand alone package and will not impact existing OpenJDK<br>
8 packages.<br>
Since this will be a tech preview, the primary JDK in Fedora 27 will<br>
continue to be OpenJDK8. OpenJDK9 is not expected to be the primary<br>
Java until Fedora 28 at least.<br>
Two problems would generally be expected with a major JDK update based<br>
on past experience:<br>
FTFBS failures due to packages having a hard-coded JDK version dependency.<br>
This was dealt with when both OpenJDK8 and OpenJDK7 were introduced<br>
over Fedora 16/17 and Fedora 19/21. Now all Java dependent packages<br>
should require java >= 1.6.0, and therefore this issue will not be a<br>
problem any more.<br>
There may be packages that rely on API that is deprecated in Java 9<br>
Such packages cannot be identified until we actually start to build<br>
with Java 9. Since Java 8 will continue to remain the primary version<br>
of Java in Fedora 26, any API deprecation issues will be a secondary<br>
problem as the main JVM will continue to be able to run everything<br>
correctly. We expect to have everything resolved well before Java 9 is<br>
to become the primary Java version in Fedora (F28 or later).<br>
