BeanCreationException : Invocation of init method failed

I am trying to implement LDAP configuration for my Spring Project but LDAP Repository is not getting initialized.

Error Trace is -

Following are dependencies-

I am not able to resolve this error. LDAP repositories base package is mentioned in applicationContext.xml but still exption follows. Please let me know for correct implimentation.

From the JavaDoc for AbstractMethodError:

Thrown when an application tries to call an abstract method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of some class has incompatibly changed since the currently executing method was last compiled.

This means the deployed version of Spring is different from the one you used to compile the code.

Make sure the deployed libraries are the same version as the ones in your IDE
