While DSpace 5 was never officially tested with Java 8 (which is why it isn't listed as "supported"), my understanding is there are several sites that are successfully running DSpace 5.x on Java 8.
This is based on the feedback reported in our Java 8 upgrade ticket https://jira.lyrasis.org/browse/DS-2653 As well as other's feedback on this mailing list, for example: https://groups.google.com/d/msg/dspace-tech/M45uwUo69W0/mBO7m50mCQAJ So, I think DSpace 5.1 will likely work on Java 8. I cannot promise it though, as it was never officially tested on that release of Java. That said, people seem to be having success at least running DSpace 5.9 on Java 8. So, if 5.1 has issues, you could upgrade to a later version of 5.x.

Thank you! On Thu, Apr 9, 2020 at 1:06 PM Jose Blanco <[email protected]<mailto:[email protected]>> wrote: Tim, Thank you! One more question. Do you think dspace 5.1 will run OK with Java 8. Our development machine is the same as our production machine, so if we upgrade that machine to use java 8, I just want to make sure it will not mess up anything with our production dspace 5.1. Thank you! -Jose On Thu, Apr 9, 2020 at 11:57 AM Tim Donohue <[email protected]<mailto:[email protected]>> wrote: Hi Jose, The error described here http://dspace.2283337.n4.nabble.com/Rest-API-not-working-in-DSpace-6-2-td4687599.html occurs because you are running a version of PostgreSQL that *requires* Java 8. So, if you want/need to run DSpace using Java 7, you'd have to find an old version of PostgreSQL that also works for Java 7. However, that may be difficult to do, as Java 7 has been end of life since 2015. It may be much much easier to just upgrade to Java 8, since whatever version of PostgreSQL you are running seems to require it.
