hi, apologies if this has been discussed already and I missed it.
I ran into this via some tets in the AccessControlManagerImplTest that trigger a NPE in the Segment MK impl [0]. I'm looking at the Tree and the NodeState interfaces, I see a lot of api docs about the returned value but no constraints about the input child name. Is null considered a valid input? Either way I think we should build in proper null checks for all existing implementations. thoughts? thanks, alex [0] https://issues.apache.org/jira/browse/OAK-635?focusedCommentId=13581138&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13581138
