Thomas Neidhart commented on SANDBOX-388:
-----------------------------------------
A rather ugly but working solution would be to cast the input graph to an
unchecked DirectedGraph to circumvent type inference at all, like the following:
{code:title=FordFulkersonTest.java|borderStyle=solid}
@Test(expected=NullPointerException.class)
public void testNullGraphAndVertices()
{
findMaxFlow( (DirectedGraph) null ).from( null ).to( null
).applyingFordFulkerson( new IntegerWeight() );
}
{code}
> Generic Type inference doesn't work in Eclipse

> {{Flow}} and {{MST}} EDSL is affected by generic type inference issue, it
> simply doesn't work in Eclipse. It works in IDEA, but in the Eclipse forum
> they reported that doesn't work if the code is compiled with Oracle JDK7.
> One of the reported error in Eclipse is:
> {quote}
> Type mismatch: cannot convert from
> SpanningTree<BaseLabeledVertex,BaseLabeledWeightedEdge<Double>,Object> to
> SpanningTree<BaseLabeledVertex,BaseLabeledWeightedEdge<Double>,Double>
