Openssl is broken in 1.8 mode due to IO::WaitReadable #1747
Description
I see some if (runtime.is1_9()) to guard around IO::WaitReadable but apparently that is not enough since I cannot load openssl in 1.8 mode:
JRUBY_OPTS="--1.8" jruby -S irb
irb(main):001:0> RUBY_VERSION
RUBY_VERSION
=> "1.8.7"
irb(main):002:0> require 'openssl'
require 'openssl'
NameError: uninitialized constant IO::WaitReadable

Side-note: someone should change guard from is1_9 to !is1_8 to reflect only 1.8 does not have this constant. This is a blocker for 1.7.13 atm.
