Release 5.1.0.8

Date: Oct 25, 2014

Juno 5.1.0.8 is a moderate update, focused primarily on performance improvements.

  • Improved performance on JSON and URL-Encoding parsers by approximately 50% on large data sets.

    • Rewrote ParserReader class to handle it's own buffering. The change allowed several optimizations to be made when dealing with JSON and URL-Encoding text by avoiding char array copies.
    • Added a estimatedSize parameter to the Parser parse methods to optimize buffering when the input size is known beforehand.

  • Revamped the BeanContext API to perform better in multi-threaded environments.

    • Introduced a new BeanPropertyStore class that handles creation of BeanContext objects. This allows BeanContext objects to be considered immutable, and therefore cacheable/reusable by the framework. While this was technically possible to cache these objects beforehand, it relied on a locking mechanism to prevent bean contexts from being modified after being created. The new mechanism is much more straightforward.

  • Modifications to the client APIs to make it easier to work with custom Apache HTTP clients.

    • Added overridable RestClient.createHttpClient() to allow customized subclasses to construct customized HTTP clients.
    • Removed the DefaultRestClient class since it's now fully redundant with RestClient.
    • Added RestClient.shutdown() method for cleaning up the internal HTTP client when you're done using a REST client.
