Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions
(1) are:
PropertyAccessException 1: org.springframework.beans.MethodInvocationException: 
Property 'exceptionProp' threw exception; nested exception is java.lang.NoSuchMethodError:   org/aspectj/runtime/internal/AroundClosure.linkClosureAndJoinPoint(I)
Lorg/aspectj/lang/ProceedingJoinPoint

Answer 1

WebSphere ships with it's own version of AspectJ Runtime. It is installed in:

base_${version}/lib/aspectjrt.jar

Flipping the class loader order from 'parent first' to 'parent last' won't work -- you'll have to take a different route.

1. Create a Shared Library (in the WebSphere Admin Console)
2. Add your version of AspectJ to this Shared Library
3. Create a new Classloader for your application or server and attach this classloader to it.

Instructions on how do to this can be found on IBM's website:
