Examples with AbstractPingerFactory org.opennms.netmgt.icmp.AbstractPingerFactory used on opensource projects

Example 1 with AbstractPingerFactory

use of org.opennms.netmgt.icmp.AbstractPingerFactory in project opennms by OpenNMS.

the class CamelBlueprintTest method doPreSetup.

/**
     * Use Aries Blueprint synchronous mode to avoid a blueprint deadlock bug. Also, make sure
     * the PingerFactory is reset so DSCP/fragment bits are cleared.
     *
     * @see https://issues.apache.org/jira/browse/ARIES-1051
     * @see https://access.redhat.com/site/solutions/640943
