Note on enforceAuthSchemes

enforceAuthSchemes at AuthenticationHelper.java:45 is an ArrayList<String> with .contains() called in isCnxnAuthenticated(). However, this list contains at most 23 scheme strings configured at startup. The O(N) cost per auth check is negligible (N is bounded and tiny). This does not rise to the level of a CWE-407 defect.
