Subject: Use Jakarta Bean Validation
X-Git-Tag: 9.0.1~9
X-Git-Url: https://gerrit.onap.org/r/gitweb?a=commitdiff_plain;h=f152c13095b6a3fcd6838cd11045c9227fb8dc34;p=policy%2Fclamp.git

Use Jakarta Bean Validation

Replace custom Policy Framework Validation with standard
Jakarta Bean Validation.

Note @NotBlank annotation behaves differently now:
- In new Jakarta framework, NotBlank implies NotNull.
- In previous framework, NotBlank allowed null values.
- Other annotations such as NotNull, Pattern, and Valid
  behave the same as before.

Issue-ID: POLICY-5509
Change-Id: Ib153db9f94bd191b837e74e1e0da9ece26c08f3c
