Ah-ha...I added some logging, which of course made the error go away...but about ten tests later I got a metaspace OOM.
That makes sense. BTW there's another source of exceptions during MethodHandle construction (e.g., JDK-8086252 [1]):
java.lang.VirtualMachineError: Out of space in CodeCache for adapters
Could be this was all just a memory issue, but it would be nice if the error didn't get swallowed.
It's not swallowed, but wrapped in InternalError before rethrowing. Do you have control over test harness to print the whole exception chain?

It has kept JRuby master CI red for many weeks. The problem does not reproduce when running in isolation...only in a long test run, and so far only on Travis CI (Ubuntu 16.something, Java 8u151). Looking at the code, it appears the dropArguments call below (called from MethodHandles.guardWithTest:3018) was replaced with some new code and dropArgumentsToMatch in 9.
