JavaHL: "Not implemented" error in StatusEditor.addAbsent

[Marc Strapetz]

One of our users has reported following Exception against Subversion 1.9.2:
Caused by: java.lang.RuntimeException: Not implemented: 
StatusEditor.addAbsent
	at 
org.apache.subversion.javahl.remote.StatusEditor.addAbsent(StatusEditor.java:110)
        ... 15 more

Actually, StatusEditor.addAbsent looks like this:

public void addAbsent(String relativePath,
                      NodeKind kind,
                      long replacesRevision)
{
  //DEBUG:System.err.println("  [J] StatusEditor.addAbsent");
  checkState();
  throw new RuntimeException("Not implemented: StatusEditor.addAbsent");
}

Is there any more debug information I should try to collect?
