addition of @Aspect causes UnsafeObjectFieldAccessorImpl

[Agent96]

Hello,

I am experimenting with AOP, I have created an annotated Apect class :

@Aspect
public class ProcessManager {

	@After("execution (* *.*(..))")
	public void startProces(JoinPoint joinPoint) {
		System.out.println(joinPoint.getSignature().getName());
	}
}

And my beans file starts off like this:

<?xml version="1.0" encoding="UTF-8"?>
<!-- 
These spring beans contain ONLY production spring beans and contain ALL spring beans 
used in the system.
 -->
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<aop:aspectj-autoproxy />
	
	
	<bean id="processManager" class="com.metadatatechnology.sdmxConsole.logging.ProcessManager" />

.....
</beans>

Unfortunately when I add the ProcessManager class I get the following error:

I have no idea what is causing this, the application works fine without the aspect - it is the addition of @After("execution (* *.*(..))") that causes it to fail.

I was using spring 2.5.6, but have now upgraded to 3.0.2 .RELEASE to try and solve the problem.

I am using spring security as well and spring flex, I have the following spring jars on my class path

spring-aop 3.0.1.RELEASE
spring-asm 3.0.1.RELEASE
spring-aspeacts 3.0.1.RELEASE
spring-beans 3.0.1.RELEASE
spring-context 3.0.1.RELEASE
spring-context-support 3.0.1.RELEASE 
spring-core 3.0.1.RELEASE
spring-expression 3.0.1.RELEASE
spring-flex 1.0.2.RELEASE
spring-jdbc 3.0.1.RELEASE
spring-orm 3.0.1.RELEASE
spring-security-acl 3.0.2.RELEASE
spring-security-config 3.0.2.RELEASE
spring-security-core 3.0.2.RELEASE
spring-security-openid 3.0.2.RELEASE
spring-security-taglibs 3.0.2.RELEASE
spring-security-web 3.0.2.RELEASE
spring-test 3.0.1.RELEASE
spring-tx 3.0.1.RELEASE
spring-web 3.0.1.RELEASE

If anyone can help I would be very very very happy....

Thanks

Ok fixed problem..In one part of the code I was autowiring a Concrete class rather then an Interface.
