Solution: If you are using maven project and added dependency in your pom.xml which is not compatible with java version then you will see above exception. Please check your newly added dependency in your pom.xml and downgrade to old version to match your java version. For example in my case I was using below dependency and getting exception:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-annotations</artifactId>
    <version>3.5.6-Final</version>
</dependency>

To fix it I downgraded to older version as below:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-annotations</artifactId>
    <version>3.3.0.ga</version>
</dependency>

You could also check latest version on maven site here
