title: k-shortest (alternative) path algorithm, java implementations
body: <p>Could you recommend any java library which implements k-shortest algorithm -> searching for alternative ways, not the only shortest one in directed multigraph ?</p>
  
  <p>I found only JGraphT but there is actually bug (which i submitted) but it will take a lot of time to fix it i guess, are there any other available implementations ? Except JGraphT i found only small one-man projects :/</p>
  
  <p>OR would be hard to modify Disjktra shortest path alg to show alternative paths ?</p>
  
  <p>Thanks</p>
