> Backporting JDK-8367901: Calendar.roll(hour, 24) returns wrong result. Fixes the roll implementation and adds a new test. Ran GHA Sanity Checks (passed) and new test (passed). The merge conflict was just the copyright header which was updated to the newer one. The new test needed to be updated for compatibility with the older JDK.

> 4. var → explicit types: Replaced var declarations with explicit types
