I am totally stuck. Do any of you guys have any clue how to resolve this??

Answer 1

Thanks to Hohenheim to point out the version issue.

Hibernate core 5.1.0.Final include dom4j-1.6.1 jar which throws this error. To fix this, need to exclude dom4j-1.6.1 from hibernate-core and include dom4j-1.6 in your pom.

I am not able find the exact reason why this is happening.

This is how I excluded dom4j from pom in hibernate dependency.

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.1.0.Final</version>
    <exclusions>
        <exclusion>
            <artifactId>jta</artifactId>
            <groupId>javax.transaction</groupId>
        </exclusion>
        <!-- Exclude SLF4j to avoid version conflicts (we have 1.6.6, this drags 
                in 1.6.1) -->
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
        </exclusion>
        <!-- Exclude dom4j to avoid version conflicts (we have 1.6, this drags 
                in 1.6.1) -->
        <exclusion>
            <groupId>dom4j</groupId>
            <artifactId>dom4j</artifactId>
        </exclusion>
    </exclusions>
</dependency>
