trying to use HWPREDICT in RRA, but when done so, I get an error when restarting opennms: does not match the required regular expression: "RRA:(AVERAGE|MIN|MAX|LAST):.*"

i've already changed the opennms config to use rrdtool like this:
org.opennms.rrd.strategyClass=org.opennms.netmgt.rrd.rrdtool.JniRrdStrategy
org.opennms.rrd.interfaceJar=/usr/share/java/jrrd.jar
opennms.library.jrrd=/usr/lib/jni/libjrrd.so

but I still get the error while trying to add this: <rra>RRA:HWPREDICT:1440:0.1:0.0035:288</rra> into: datacollection-config.xml
