`List.of()` along with `Set.of()` create unmodifiable `List/Set` but with smaller footprint comparing to `Arrays.asList()` / `new HashSet()` when called with vararg of size 0, 1, 2.
In general replacement of `Arrays.asList()` with `List.of()` is dubious as the latter is null-hostile, however in some cases we are sure that arguments are non-null. Into this PR I've included the following cases (in addition to those where the argument is proved to be non-null at compile-time): - `MethodHandles.longestParameterList()` never returns null - parameter types are never null - interfaces used for proxy construction and returned from `Class.getInterfaces()` are never null - exceptions types of method signature are never null ------------- Commit messages: - 8282662: Use List/Set.of() factory methods to save memory Changes: https://git.openjdk.java.net/jdk/pull/7729/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=7729&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8282662 Stats: 22 lines in 8 files changed: 1 ins; 3 del; 18 mod Patch: https://git.openjdk.java.net/jdk/pull/7729.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/7729/head:pull/7729 PR: https://git.openjdk.java.net/jdk/pull/7729
