The service throws an NPE when using older versions of rrdtool.
This case should be handled properly and an error of the form "Use rrdtool v1.4.0 or greater" should be logged instead.
Stack trace:
java.lang.NullPointerException at org.opennms.web.rest.measurements.fetch.RrdtoolXportFetchStrategy.fetchMeasurements(RrdtoolXportFetchStrategy.java:177) ~[org.opennms.features.rest-measurements-api-16.0.0.jar:?] at org.opennms.web.rest.measurements.fetch.AbstractRrdBasedFetchStrategy.fetch(AbstractRrdBasedFetchStrategy.java:113) ~[org.opennms.features.rest-measurements-api-16.0.0.jar:?] at org.opennms.web.rest.MeasurementsRestService.query(MeasurementsRestService.java:155) [org.opennms.features.rest-measurements-api-16.0.0.jar:?]
