I see an Error thrown by Dila when running on the dacapo bloat benchmark. To reproduce, follow the instructions in Ticket 2, except use the following command line:

java -Xmx1000M -cp dacapo-2006-10-MR2.jar:/Users/manu/workspaces/dilaWorkspace/dila.javaagent/lib/agent.jar dila.wrapper.Dila Harness TestsRun.cfg -s small bloat

The error stack trace is as follows:

java.lang.Error: Should not happen: Static dispatch target could not be found!

I set a breakpoint there, and it looks like the dispatch map for

loadClass(Ljava/lang/String;)LEDU/purdue/cs/bloat/reflect/ClassInfo;

is missing an entry for class

LEDU/purdue/cs/bloat/context/BloatContext;

Before running, you may want to comment out the two method calls that dump output before the error is thrown in Hierarchy; for me, those lines dumped around 50MB of output.
