Symptoms:

While running Embedded Pulse on a cache member based on Spring Data GemFire configuration, you can see the following error and Embedded Pulse will fail to start with a "javax.validation.ValidationException: Unable to find a default provider":

Environment

Cause

This is caused by the lack of implementation of a Bean Validator based on JSR-303, which is internally required for Spring Framework.

Resolution

Add the Hibernate Validator jars to the CLASSPATH when starting your GemFire cache with Embedded Pulse.

If you use Maven, you can add the following entry into your pom.xml file as a dependency.

<dependency>
  <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
  <version>5.2.1.Final</version>
</dependency>
