Contrary to checkstyle, SpotBugs SF_SWITCH_FALLTHROUGH check does not detect an intentional commented //fallthrough  in a switch/case structure and reports a warning/error.

To remove this false positive, edu.umd.cs.findbugs.annotations.SuppressFBWarnings needs to be imported so that the
@SuppressFBWarnings("SF_SWITCH_FALLTHROUGH") decorator can be put in front of the related block.

In the example below
https://git.opendaylight.org/gerrit/c/transportpce/+/87675/4/networkmodel/src/main/java/org/opendaylight/transportpce/networkmodel/NetConfTopologyListener.java
doing so burdens the code

As the same check is already better performed by checkstyle, the SF_SWITCH_FALLTHROUGH SpotBugs check (and maybe some others) should probably be removed from ODL-parent.
