I've reproduced your crash from the command line; thanks for the clean
instructions.
The crash is for:
def foo(a); end; a = 1; while a < 1_000_000; foo(a); a += 1; end
There is a basic nbproject in the jruby repo, but no debug or run
targets.
Is there a secret combination to getting a debugger session on the
equivalent of this command line?
bin/jruby --server -J-XX:+EnableInvokeDynamic -J-
Djruby.compile.invokedynamic=true script.rb
Thanks!
