Answer 1

This happens when the supplied library version is not having the classes required. There is no general fix though but you can try with this approach which worked for me.

All you need to do is to have a proper exclusion of ASM libraries from hibernate and a separate inclusion of it. Seems fuzzy but take a look at the snippet from a working pom.xml. The intent behind this approach is to include a more later version of the dependent library which may be required by some other 3rd library in the project.

for including hibernate entity manager i am using following code.

    <dependency>
     <groupId>org.hibernate</groupId>
     <artifactId>hibernate-entitymanager</artifactId>
     <version>${hibernate.version}</version>
    <exclusions>
        <exclusion>
         <groupId>asm</groupId>
         <artifactId>asm</artifactId>
        </exclusion>
      </exclusions>
    </dependency>

Here I am explicitly excluding asm from the hibernate-entity manager inclusion and next to it I am including it separately

    <dependency>
      <groupId>asm</groupId>
      <artifactId>asm</artifactId>
      <version>${asm.version}</version>
    </dependency>

and the properties are. These version choices worked for me in the latest project.

    <properties>
            <hibernate.version>3.6.0.Final</hibernate.version>
            <asm.version>3.3</asm.version>
    </properties>

Hope, this solves your problem.
