Possible loop in thredds.client.catalog graph?

[JohnLCaron]

Adding this method to DatasetNode: @Override public String toString() { return MoreObjects.toStringHelper(this) .add("parent", parent) .add("name", name) .add("flds", flds) .toString(); }

causes a test failure:

thredds.server.cdmr.TestCdmRemoteServer2.testUrlReading
