Here's the full actual error that seems to cause the timeout. It does seem
to be related to this change, but it seems like something _uncovered_ by this
change.
My interpretation is that `isInterpreter` has been _true_ during tests all
this time (hitting the `ClassNotFoundException` path) and now it's using this
code path calling the constructor, which maybe has a problem.
I don't know a lot about the reason for this difference in handling the two
paths.
