We discovered a bug in the BlockGraph code in beta.5 due to some legacy
code.  I think this causes the problem you're experiencing.

In soot.toolkits.graph.BlockGraph, you need to remove all references to
"blockDeltaHeight".  Some references cast "Unit" to "Inst", which doesn't
necessarily go through.

We will be releasing another beta next Tuesday, including a whole bunch of
nifty stuff; for instance, the fix to this bug.
