Rubygems broken due to psych problem for 1.7.16 in 1.8 mode #2057
Description
Script to reproduce that emulates what Rubygems' load_yaml does:
JRUBY_OPTS=--1.8 jruby -rubygems -e '
begin
gem "psych"
rescue Gem::LoadError
end
begin
require "psych"
rescue LoadError
warn $!.to_s
end
'Instead of a LoadError because psych isn't available on 1.8, we get:

This breaks the simplest of Rubygems operations on the command-line, such as:
JRUBY_OPTS=--1.8 gem env path
