> Backporting 8318613: ChoiceFormat patterns are not well tested. The new test checks, both correct and incorrect patterns, the behavior of incorrect patterns that either throw an IllegalArgumentException or discard the incorrect portion, and the case of formatting with an empty pattern (that leads to empty limits and formats). Ran GHA Sanity Checks (1 unrelated test failure - java/lang/ProcessBuilder/Basic.java#id0) and adjusted test (passed). Patch is clean.
