This problem is due to incorrect version of “hibernate-validator” dependency. You need to try other versions of this dependency to solve this issue. Below combination works perfectly.

<dependency>
  <groupId>javax.validation</groupId>
  <artifactId>validation-api</artifactId>
  <version>1.0.0.GA</version>
</dependency>
<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-validator</artifactId>
  <version>4.3.1.Final</version>
</dependency>

If you want to refer pom.xml, please refer this article:- https://howtodoinjava.com/spring-mvc/solved-java-lang-noclassdeffounderror-could-not-initialize-class-org-hibernate-validator-engine-configurationimpl/
