[CONTROLLER-1472] NullPointerException in Devices.java

Tue, 25 Jul 2023 08:24:06 +0000

I located one concurrency bug will raise NullpointerException inside Devices.java.

The snippet for the bug:

String nodeConnectorName = ((Name)switchManager.getNodeConnectorProp(nodeConnector,
Name.NamePropName)).getValue();

the switchManager.getNodeConnectorProp() function potentially returns a Null if a concurrent removal upon the property variable.
A null checker can fix this bug.
