> I noticed two small possibilities for improvement in DataDictionaryImpl.getRoutineList()
when I worked on DERBY-5730:
> - The method always returns a list of one or zero items. Instead of creating an ArrayList,
it should use Collections.singletonList() and Collections.EMPTY_LIST, which are more memory-efficient.
> - It loops through the entire SYSFUN_FUNCTIONS array, even if the matching function is
found in the first cell of the array. It should break out of the loop once a match is found.
