puts IO.read(_FILE_) { "fail" }

should ignore the fail. It does not and instead raises an exception because for some insane reason the block is passed to IO.open.

The attached patch fixes the problem but needs to be cleaned up.

The error message given is this

org.jruby.RubyIO:2801:in `read': java.lang.ClassCastException: org.jruby.RubyString cannot be cast to org.jruby.RubyIO
