Overview

This is a follow-up to #30185 and #33151.

When applications run on JDK 23+, Spring Framework should support lenient parsing for date/time formats that include the time period (AM or PM) -- for example, by matching leniently against a narrow non-breaking space (NNBSP) or a standard space between the hour and AM/PM declaration.
