this poorly optimised bytecode causes soot to crash

[Rohan Hart <rohan.hart@peace.com>]

Hi, I'm trying soot (2.0.1) out on some bytecode produced from the
Java-alike language Nice.  However the non-optimal bytecode

   0 invokestatic #12 <Method long f()>
   3 new #14 <Class java.lang.Long>
   6 dup_x2
   7 dup_x2
   8 pop
   9 invokespecial #17 <Method java.lang.Long(long)>

confuses soot because it thinks it's trying to cast a Long into a
primitive long.  The result is two
  soot.jimple.toolkits.typing.TypeException: Type Error(12)

Here's the (equivalent) bytecode produced by similar code in Java

   0 new #2 <Class java.lang.Long>
   3 dup
   4 invokestatic #3 <Method long f()>
   7 invokespecial #4 <Method java.lang.Long(long)>
