  • Field Details

    • DEFAULT_RESOURCE

      private static final String DEFAULT_RESOURCE
      Default name for resource bundle containing the messages.
      See Also:

    • defaultResource

      private static ResourceBundle defaultResource
      Cached resource bundle containing the messages.

      ResourceBundle does caching internally but this caching involves a lot of string operations to generate the keys used for caching, leading to a lot of StringBuffer reallocation. In one run through the complete jTDS test suite there were over 60000 allocations and reallocations (about one for each get() call).
