Could you try adding the following lines to your code?

VertexCentricConfiguration parameters =3D new VertexCentricConfiguration();
parameters.setSolutionSetUnmanagedMemory(true);

return graphWithScoredVertices.runVertexCentricIteration(new
VertexLabelUpdater(delta),
      new LabelMessenger(), maxIterations, parameters);

Change the functions appropriately in the runVertexCentricIteration call.
The error seems to be caused by this CompactingHashTable and this parameter
deactivates its usage. I am very curious what happens in your case. If you
could tell us the outcome, I'd greately appreciate it.
