@NotNull annotation is not checking null querypara

Question

I am trying to use javax.validation.validation-api for validating @QueryParam parameters. I have followed steps as below:

1. Added dependency:

   <dependency>
       <groupId>javax.validation</groupId>
       <artifactId>validation-api</artifactId>
       <version>1.1.0.Final</version>
       <scope>provided</scope>
   </dependency>
   <dependency>
       <groupId>org.glassfish.jersey.ext</groupId>
       <artifactId>jersey-bean-validation</artifactId>
       <version>2.12</version>
       <exclusions>
           <exclusion>
               <groupId>org.hibernate</groupId>
               <artifactId>hibernate-validator</artifactId>
           </exclusion>
       </exclusions>
   </dependency>
   

2. Jersey resource:

   @GET
   @Produces(MediaType.APPLICATION_JSON)
   @Path("/{param1}")
   @ValidateOnExecution
   public SomeObject get(@PathParam("param1") String param1,
       @NotNull @QueryParam("q1") String q1,
       @NotNull @QueryParam("q2") String q2) {
   
       try {
           //Assuming q1 and q2 are NOT Null here
           ...
       } catch(Exception exception) { 
           throw new WebApplicationException(exception, 
                   Response.Status.INTERNAL_SERVER_ERROR);
       }
       return someObject;
   }     
   

3. I tried giving various combination of URLs as in q1 and q2 both parameters absent, q1 absent or q2 absent. Each time, @NotNull is not getting detected. Means try block code is getting executed irrespective of q1 and q2 being null.

What else needs to be done?

I referred this link - https://jersey.java.net/documentation/latest/bean-validation.html#d0e11956.
