I do wonder if some organizations are holding off until Oracle Java 11 LTS
arrives in September - It will be interesting to see what happens then.
Regarding Java 11 support in GeoServer:
The GeoTools proposal is here: https://github.com/geotools/geotools/wiki/
Java-9-Compatibility, and still has a number of outstanding issues that
will affect GeoServer.
There is not currently an equivalent GeoServer proposal.
When I tried running GeoServer on Java 9 back in February, I was able to
get it to compile, but ran into numerous test/runtime failures due to
changes in reflection. One of the major culprits is the Spring framework -
support for newer Java versions will require an upgrade to Spring 5; this
will probably be the largest part of the GeoServer upgrades. (Hazelcast
also has a bunch of similar issues).
One other note: The initial tests on Java 9 required a number of runtime
parameters that are not available in Java 11; see the GeoTools proposal for
more details about what needs to be done to get things working without
these parameters.
I think a winter code sprint focusing on the Java upgrade would be useful.
