  # Modifying the @cache hash under JRuby - even with a `synchronize do`
  # block and a `Hash#dup` operation - has been known to cause issues
  # with JRuby for concurrent access of the hash while it is being
  # modified. The hash really only needs to be modified for the benefit
  # of the security agent, so if JRuby is in play and the security agent
  # is not, don't attempt to modify the hash at all and return early.
