Digging more deeply, it looks like we do have BOTH Jersey 1 and Jersey 2 now in our POMs.

https://github.com/DSpace/DSpace/search?l=maven-pom&q=jersey&utf8=%E2%9C%93

1) Jersey-Server v1 is used by REST
2) A reference to Jersey-Client v2 came into the 'dspace-api' via DS-2880 (PubMed integration), which was merged in the last week or so:
https://jira.duraspace.org/browse/DS-2880
Here's the commit: https://github.com/DSpace/DSpace/commit/002b8783bffd15024f9827d5166f1e0cb52a95ce

So, I think Bram's guess may be correct. We may have a Jersey version conflict on "master".

Hi Terry,

not sure what it is, but the following stackoverflow thread seems to indicate this means that you're trying to load Jersey 1 and 2 at the same time:
http://stackoverflow.com/questions/23277429/exception-in-rest-jersey

The error only matches on

/java.lang.AbstractMethodError: javax.ws.rs.core.UriBuilder.uri(Ljava/lang/String;)Ljavax/ws/rs/core/UriBuilder;/
/        at javax.ws.rs.core.UriBuilder.fromUri(UriBuilder.java:119)/
/
/
So I'm not 100% confident the issues are related.

    I would like to do some testing with the Enhanced Configurations code.

    I deployed the latest code on the master branch to my test server
and I am seeing the following error when I tried to access /rest. I can access /xmlui, /solr, and /oai.

    I believe that I have created a proper local.cfg,

    Can you offer any advice?
