E.g.
Foo[] x = new Foo[] { ... };

Also,
Foo[] x = new Foo[0];
// can be rewritten to
Foo[] x = {}; // I think this should probably be opt-out, since new Foo[0] is very readable
This is only possible in local variable or field declaration initializers, in all other contexts, the new Foo[] is mandatory. E.g. the following is disallowed:
The rule would belong in the code style category.
I read on stackoverflow that this lighter syntax is not from the original Java 1.0 spec but probably from 1.1, but we don't have language versions below 1.3 anyway. Recent JLS: https://docs.oracle.com/javase/specs/jls/se8/html/jls-10.html#jls-10.6
