# Inliner used to assign exact type to the artificial multiple-return phi if the
# class type was final which does not hold for arrays.

# The type information is only used by recursive calls to the inliner and is
# overwritten by the next pass of reference type propagation. Since we do not
# inline any methods from array classes, this bug cannot be triggered and we
# verify it using Checker.
