String literal difference from MRI #5052
Running on Windows 10
The "WARNING" are a Java 9 thing about us using reflection to crack open core JDK classes, and the stack trace is a known bug with readline on Windows that's fixed in 22.214.171.124, so I'll remove those from your description.
The actual string bug should have a fix shortly; I believe @enebo is on it.
