* KeyUtil.getKeyBytes(String) was being called twice for every Key, causing unnecessary byte[] allocations. * flags is more often than not 0, therefore send 0 as a String vs. an int to avoid autoboxing the int to an Integer and requiring unnecessary String.valueOf(Integer) + Integer.toString() allocations. * exp is commonly 0 (for never expire), and therefore send 0 as a String vs. an int to avoid the same issue mentioned above for flags. If flags is 0 and exp is 0, ~10% less garbage is allocated as a result of this optimization.
