[Soot-list] NullPointerException on FastHierarchy.isSubClass

[Marc-Andre Laverdiere-Papineau]

Hello,

I have a test case that reproduces the issues all the time, but it is 
not very small :$

I can try synthetizing a tinier one and send over.

Right now, what I can see is that the SootClass instance has a null 
superclass, even though it extends org.apache.jasper.runtime.HttpJspBase.

Is there an option that would disable/enable the tracking of superclasses?
