[Soot-list] UnitThrowAnalysis throws exception

[Fei Yan]

Hi All,

When I try to use UnitThrowAnalysis, it throws certain exceptions which 
really confused me:

with the whole program to be false, I got
java.lang.NullPointerException
	at soot.AnySubType.v(AnySubType.java:43)
	at 
soot.toolkits.exceptions.ThrowableSet$Manager.<init>(ThrowableSet.java:240)
	at 
soot.Singletons.soot_toolkits_exceptions_ThrowableSet_Manager(Singletons.java:765)

	at soot.SootMethod.getBodyFromMethodSource(SootMethod.java:82)
	at soot.SootMethod.retrieveActiveBody(SootMethod.java:329)

and with the whole program to be true, I got
java.lang.NullPointerException
	at soot.toolkits.exceptions.ThrowableSet.add(ThrowableSet.java:556)
	at 
soot.toolkits.exceptions.UnitThrowAnalysis.<init>(UnitThrowAnalysis.java:48)

Anybody had experience regarding to this?

Many many thanks!
