Unable to initialize 'javax.el.ExpressionFactory' on GAE while validating

I am making app in Java8 on GAE. I Use Gson to serialize and deserialize jsons to pojo and I wanted to use javax.validation for validating those POJOs. No spring or anything else here. I found that common implementation is Hibernate validator. So my pom contains after many searches this:

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.0.Final</version>
</dependency>
<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>6.0.2.Final</version>
</dependency>
<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator-annotation-processor</artifactId>
    <version>6.0.2.Final</version>
</dependency>
<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.el</artifactId>
    <version>3.0.1-b08</version>
</dependency>

and 

instance.factory = Validation.buildDefaultValidatorFactory();

is null

and log shows

javax.validation.ValidationException: HV000183: Unable to initialize 'javax.el.ExpressionFactory'. Check that you have the EL dependencies on the classpath, or use ParameterMessageInterpolator instead

This helped to me. Add this dependencies to your pom.xml

    <dependency>
        <groupId>org.glassfish</groupId>
        <artifactId>javax.el</artifactId>
        <version>3.0.1-b08</version>
        <scope>test</scope>
    </dependency>
