Constants dont produce facts when passed through the body

[Laschoking]

The first example produces 1 fact, while the second example produces not facts, which is unexpected.

HeapAllocation_Type("<<main method array>>", "java.lang.String[]").

HeapAllocation_Type(?heap, ?type) :-
  ?heap = "<<main method array>>",
  ?type = "java.lang.String[]".
