This script works fine with MRI, but throws a AIOBE when JRuby is used:
#!/usr/bin/env jruby
ma = %w[bar bar= foo_bar foo_bar= baz baz= foo_baz foo_baz=]
p "This re is fine: /bar.*/"
gma = ma.grep(/bar.*/)
p "This re is fine: /bar.*$/"
gma = ma.grep(/bar.*$/)
p "This re fails: /bar.*\\b/"
gma = ma.grep(/bar.*\b/) # exception raised here
p "start: #{ma.inspect}"
