Java Library with subgraph isomorphism problem support?
<p>I'm trying to analyze the usage of "#include" in C files (what is included first, dependencies...).</p>

<p>To do so, I extract from a C file the "#include" and I'm building a graph. I would like to identify common patterns in this graph...</p>

<p>So far, I'm using JGraphT as the graph engine (not sure this is the correct expression) and JGraph for the rendering (however using jgraph is a bit problematic since the Layouts are no longer included in the free release). </p>

<p>I've been unable to find any isomorphism support in jgrapht. Do you know any solution providing this kind of support (something like igraph but for java)..?</p>

<p>I'm using java 1.5 and the proposed solution must be free...</p>
