Bumps org.apache.httpcomponents.client5:httpclient5 from 5.1.4 to 5.2.1.

Changelog

Sourced from org.apache.httpcomponents.client5:httpclient5's changelog.

Release 5.2.1

This is a maintenance release that fixes several regressions found in release 5.2.

Change Log

• Regression: Async execution runtimes set the negotiated protocol version in the execution context at the wrong point of request execution. Contributed by Oleg Kalnichevski

• Cancel connection request on exception. Contributed by Bryan Keller

• Replace deprecated use of LangUtils#equals() with Objects.equals(). Contributed by Gary Gregory

• Regression: Multipart body builder and multipart formatters fail to escape special characters such as backslash and quote mark. Contributed by Oleg Kalnichevski

Release 5.2

This is the first GA release in the 5.2 release series. This release finalizes the 5.2 APIs and corrects a number of defects discovered since the previous release.

Please note that 5.2 upgrades the minimal JRE level to version 8 (8u251 is required).

Please note this is likely to be the last release series with support for SPNEGO and NTLM authentication. As of version 5.3 GSS-API-based authentication schemes (Kerberos, SPNEGO) and NTLM authentication schemes are going to be deprecated and disabled by default.

Notable changes and features included in the 5.2 series:

• Upgrade to Java 8.

• Improved support for TLS upgrade and HTTP protocol upgrade (async).

• Support for H2 tunneling via HTTP/1.1 proxy.

• Conformance to RFC 7617 (The 'Basic' HTTP Authentication Scheme).

• Migration to Java 8 Time primitives in State Management and Cache APIs.

• Connection and TLS configuration on a per route basis.
