Default value of "merge-policy" xsd attribute has an unstable name like org.infinispan.conflict.MergePolicies$$Lambda$72/520956294 ---------------------------------------------------------------------------------------------------------------------------------- Key: ISPN-8530 URL: https://issues.jboss.org/browse/ISPN-8530 Project: Infinispan Issue Type: Bug Affects Versions: 9.1.0.Final Reporter: Adrian Nistor Assignee: Ryan Emerson Fix For: 9.2.0.Final A different lambda name gets generated during each build. So an xsd created and deployed to http://docs.jboss.org/infinispan/schemas/ becomes out of sync after next build. We can fix that by redeploying the schema but we cannot assume users will always re-fetch it. Using static inner classes (non-anonymous) would be preferable in this case even though the lambda code looks nicer. This solution maintains backward compat with 9.1 too.
