The javadoc comment in com.liferay.portal.service.impl.GroupServiceImpl says "params the finder params (optionally <code>null</code>)." Passing a null value causes a nullpointer exception because MapUtil.toLinkedHashMap(params) gets called immediately. Needs to either catch the null or have the comment edited.
