Spring 3.1 entityManagerFactory java.lang.NoSuchFieldError: NULL Error

Question

I have just migrated Spring 3.0.5 to 3.1 GA. I faced runtime error during initialization:

org.springframework.beans.factory.BeanCreationException: Error crea         


        

Answer 1

It may help you. Upgrading from Spring 3.0.3.RELEASE results in: java.lang.NoSuchFieldError: USER_DECLARED_METHODS

Earlier I had like this

    org.springframework
    spring-core
    3.1.2.RELEASE

...

Then I added

    org.springframework
    spring-core
    3.1.2.RELEASE
    
        
            org.springframework
            spring-core
