> OGNL example: S2-029 leak:
> #_memberAccess.excludedClasses=#{}.keySet() it has been fixed.
> But now we can direct change the _memberAccess in the OGNLContext
> #_memberAccess=@ognl.OgnlContext@DEFAULT_MEMBER_ACCESS
> woo.. it can round the SecurityMemberAccess.isAccessible checking, because
> modify the OGNLContext member _memberaccess that NOT check the accessible.
