Hamcrest v4.0

[tumbarumba]

This issue is for planning and discussion of features and fixes that will go into Hamcrest v4.0. Although v3.x will maintain compatibility with Java 8, v4.0 relax this rule and allow for matchers related to language features introduced after Java 8.

Candidates:

• [ ] Multi-release jar files (https://openjdk.org/jeps/238)
• [x] #392

See also:

• #417

Will #392 stay with this release or be moved to v3.1(#417)?

Please, release it :)
