This is to improve thread safety for static methods that may be called from multiple threads. This change does not affect the thread safety of individual HttpRequest instances. Use ThreadLocal for trustedFactory, as the documentation for the classes used makes no thread- safety guarantees. Make TRUSTED_VERIFIER final and initialize lazily using the lazy initialization holder class idiom used in Effective Java item 71, as the implementation used is thread-safe. Make connectionFactory volatile. This requires implementers of the ConnectionFactory interface to ensure that their implementation is thread-safe. This also changes the static members used that were not final to use the more conventional camelCase naming rather than ALL_CAPS.

Nope, sorry for the delay, will merge it soon. Do you think it is feasible to add any tests for this that will prove these changes are needed? |

@rferreira are you having threading issues using this library? |

@kevinsawicki nope, just a small false alarm a few weeks back. |
