1.22.0 (2021-11-05)

Features Added

• Added ReferenceManager which is capable of performing Cleaner-like functionality by allowing a Runnable callback
  to be triggered when an object reference is eligible for garbage collection.
• Added RequestOptions which allows for a chained set of operations to be applied to an HttpRequest before being
  sent through the HttpPipeline.
• Added an ETag class which represents an HTTP ETag.
• Added getJavaClass method to retrieve the representing instance of the TypeReference created.
• Added support for HTTP method OPTIONS by adding an Options annotation.
• Added a function to CoreUtils which merges two Contexts together.
• Added a new feature flag AZURE_JACKSON_ADAPTER_USE_ACCESS_HELPER which indicates to JacksonAdapter to wrap
  serialization calls in AccessController.doPrivileged to prevent SecurityManager exceptions when JacksonAdapter
  has the prerequisite permissions.

Bugs Fixed

• Fixed a bug where an initial length of 0 wasn't permitted when creating a ByteBuffer collector.
• Fixed a bug where an exception type would be instantiated and never used in a hot path, reducing memory usage.
• Fixed a bug where the content length of a serializable request body may return null when it is known (already serialized).

Other Changes

• Improved performance of operations that merge or retrieve all values of Context.
