• • • Summary ***
      The output topology may on occassion miss a termination point(s), supporting node(s), or any other item(s).
      This usually results in failing of a system test case.

• • • Example ***
      An example can be seen in topoprocessing-csit-verify-1node-topology-operations job run nr. 146 [1].
      The test "Link Computation Aggregation Filtration" failed because the output topology lacked a supporting node.

Log evidence:
Trace evidence of the bug can be seen in the karaf logs.
On line 6737 of the karaf log [2] the output node:2 contains the proper amount of supporting nodes.
However, on line 6752 is the UnderlayTopologyListener processing the node:2 again for no apparent reason, only with the aforementioned supporting-node already missing.
