Avoid final field mutation in CapturedSnapshotTest #10440

sarahchen6 · 2026-01-23T20:13:20Z

What Does This Do

Add a test-only TEST_INSTANCE to the CorrelationAccess class. Now instead of mutating a final field in CapturedSnapshotTest to introduce a spy, we can set the spy to be a non-final TEST_INSTANCE.

Motivation

Mutating final fields will introduce warnings starting in Java 26 and be disallowed in a later release (JEP 500).
