Thanks for the PR @Pepo48 . I plan to review later today/tomorrow. I'm wondering if this issue affects schema handling generally and not just for parameters. E.g. does it happen for a property within another schema as well?

@MikeEdgar I also wondered about this earlier and at least based on what I see from my research is that it doesn't affect schema properties. The POJO property pipeline handles this correctly via TypeProcessor.processType(), which resolves enums before @Schema is read.

The bug is in mapParameterSchema() in AbstractParameterProcessor, which handles all parameter types, not just @BeanParam fields. Verified on @QueryParam and @HeaderParam, both as @BeanParam fields and direct method arguments. In all cases, parameterHasSchema() returns early when any schema object exists, skipping type resolution entirely.

But, please, recheck this thoroughly, just to be on the safe side. 😊
