I've been running dspace 1.6 through 3.0 on OpenJDK 6 from Debian
repository in production without problems.
To see the particular problems with 1.8 and JDK 7 that were fixed in 3.0,
there's a Jira issue you can find in the 3.0 release notes.

Hello,
I have got a new instance of Ubuntu 12.04 LTS Precixe Pangolin to run
our DSpace instance on.
We currently use DSpace 1.8.2 and have not decided when we will find the
time to move on to DSpace 3.0 which is a major task for a project
effectively run by two people in their spare time.
Comparing installation requirements of versions 1.8.2 and 3.x, the 1.8
branch still reports issues with Java 7 because of solr incompatiblity and
further recommends to use SUN/Oracle JDK 6.
Using SUN/Oracle JDK means installing manually without support by the
distributions package management which I suspect is the same issue for
every OS distribution since it is triggered by Oracles licensing terms.
Installing manually means that I will run into trouble as soon as I move on
to DSpace 3.0 and OpenJDK 7, a situation discouraging future updates
besides of keeping up to date manually until then.
Using OpenJDK 6 would be a minor issue as compared to using either
SUN/Oracle JDK 6 or 7, because it is still in the package management.
Although the version available there is the 13 month old b24, whereas the
latest Version of OpenJDK6 is the two month old b27 which likely fixes
numerous security issues. This means that it is certainly not advisable
either to use OpenJDK6.
I am eager to learn, whether the issues with Java7 and solr have been
fixed in a way that might encourage me to ignore the warning in the DSpace
1.8 install docs an just try to use Java 7 with DSpace 1.8 branch.
Furthermore, is there anybody running DSpace 1.8 who tried OpenJDK, either
OpenJDK 6 or OpenJDK7? When did you try? Within the last six month or
before? If you tried within the last six month, which obstacles did you run
into and were you able to solve them? Are there any notes online for
further reading? A quick search did not return anything of interest.
Thanks a lot, Christian
