CVE-2012-5370 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-5370):
  JRuby computes hash values without properly restricting the ability to
  trigger hash collisions predictably, which allows context-dependent
  attackers to cause a denial of service (CPU consumption) via crafted input
  to an application that maintains a hash table, as demonstrated by a
  universal multicollision attack against the MurmurHash2 algorithm, a
  different vulnerability than CVE-2011-4838.

As far as I can tell this is fixed in jruby 1.7.1, but we are still providing 1.6.x.

jruby 1.6 is now masked for removal.
