Commit 59447f3 ("Fixes wrt [core#1378]") added a START_ARRAY guard plus two tests to the jsr-353 `JsonPatchDeserializer`, but the jakarta-jsonp copy was never updated. Without the guard `_deserializeArray()` reads past the end of the document and switches on the resulting `null` token, so non-Array input fails with a bare NPE instead of `InvalidFormatException`: input jsr-353 jakarta-jsonp "op" InvalidFormatException NullPointerException: ... "t" is null 42 InvalidFormatException NullPointerException Port the guard verbatim and bring over the two tests (plus one for numbers). Also add the `a2q()` helper to `TestBase` for the new test content. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

START_ARRAYguard — plus two tests — tojsr-353'sJsonPatchDeserializer, but thejakarta-jsonpcopy of the same class was never updated. The two modules have drifted.Without the guard,
