…generates minItems:1
…requiredMode When @notempty or @notblank annotations were combined with @Schema(requiredMode = REQUIRED) or @Schema(requiredMode = NOT_REQUIRED), the minItems and minLength constraints were not being generated in the OpenAPI schema. This was caused by the applyNotNullAnnotations flag incorrectly gating the entire @NotEmpty/@notblank processing block. The flag should only control whether the field is added to the required list, not whether minItems/minLength are set. The fix separates these concerns: - minItems/minLength are always applied when @NotEmpty/@notblank are present - updateRequiredItem() is only called when applyNotNullAnnotations is true Fixes regression introduced between 2.2.40 and 2.2.41.

Description
When
@NotEmptyor@NotBlankannotations are combined with@Schema(requiredMode = REQUIRED)or@Schema(requiredMode = NOT_REQUIRED), theminItemsandminLengthconstraints are not being generated in the OpenAPI schema.Root cause: The
applyNotNullAnnotationsflag was incorrectly gating the entire@NotEmpty/@NotBlankprocessing block. This flag istrueonly whenrequiredMode == AUTO, so when users explicitly setrequiredModetoREQUIREDorNOT_REQUIRED, the validation constraints were completely skipped.The fix: Separates the concerns:
minItems/minLengthare always applied when@NotEmpty/@NotBlankare presentupdateRequiredItem()is only called whenapplyNotNullAnnotationsis trueThis is a regression introduced between 2.2.40 and 2.2.41.
