[jira] [Created] (OAK-8270) Add variant of PermissionUtil.getReadOnlyTree that never returns null

angela created OAK-8270:
---------------------------

             Summary: Add variant of PermissionUtil.getReadOnlyTree that never returns null
                 Key: OAK-8270
                 URL: https://issues.apache.org/jira/browse/OAK-8270
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: core, security
            Reporter: angela
            Assignee: angela


the current implementation of {{PermissionUtil.getReadOnlyTree}} may have a null tree passed and will in this case return {{null}}, which is not suited for those parts of the permission evaluation where the {{Tree}} cannot be null and a non-null return-value is therefore expected.

[~stillalex], i would therefore suggest to rename the existing method to {{getReadOnlyTreeOrNull}} and add a variant that never returns null. see attached patch.
