No red flags from me.

A minor pet peeve about the code style in Hotspot, which adds up to
accidental code complexity: pro-actively blowing up more methods than
required to solve the task at hand.

This change provides the example: both compute_injected_fields() and
has_injected_fields() do dances around _has_injected_fields value. It
would seem more readable to just have has_injected_fields() to lazily
compute the value on demand, inlining both compute_injected_fields() and
compute_injected_fields_helper(). That would spare two additional
methods, and make the code generally more readable, and maintainable.

Thanks,
-Aleksey.
