Hello from JRuby and here's another crash

[John Rose]

Great to hear from you, my old friend, and thanks for kicking the tires. 
  Sorry one of them blew out on you.  We’ll look at it with interest.

For the first time ever, I am unable to attend JVMLS, so I’m sorry I 
will miss seeing you there.

It is possible that our indy filters are set wrong; our optimizations 
work for indy BSMs defined by java.base, but perhaps not for yours.
