Type: Bug
Resolution: Done
Priority: Major

Steps to Reproduce:
Hide

Deploy my sample attached application and make following HTTP requests:

Valid HTTP GET request:

localhost:8080/test-war/api/admins/?page=1&pageSize=1

causes unwanted internal exception javax.validation.UnexpectedTypeException:

400 BAD REQUEST { "success": false, "errors": [ "HV000030: No validator could be found for type: resteasy.bug.showcase.params.IntParam." ] }

While invalid HTTP GET request:

localhost:8080/test-war/api/admins/?page=-2&pageSize=-2

causes proper validation and desired output:

422 Unprocessable Entity { "success": false, "errors": [ "page must be greater than or equal to 1", "pageSize must be greater than or equal to 1" ] }

Workaround Description:

Hide

Switching to xml approach: META-INF/validation.xml and removing validation configuration (mainly custom constraint mapping) from my custom @Provider class (I mean resteasy.bug.showcase.ValidationConfigurationContextResolver) causes the bug to disappear. Validation is then performed correctly.

Description

See attached sample small project test.zip.

Bug is about using built-in @javax.validation.constraints.Min constraint annotation for validating my custom type: resteasy.bug.showcase.params.IntParam but only when configuring validation within @Provider class. Hibernate-validator cannot find my validator when request is valid - but in the same time can find it when a request is invalid.
