[aspectj-users] NPE while using LTW in tomcat.

["Shashikant Kale" <Shashikant.Kale@xxxxxxxxxxxxxxxx>]

Hi,

 

I am using aspectj LTW (aspectjweaver-1.6.1) for weaving an aspect available in another jar within my web application code.

 

While building the jar which contains the aspect, using maven, I have JUnits which run without any problems using LTW.

 

My aspect code looks as below

      @Around("execution (@com.arisglobal.aglite.annotations.OperationTrail public * *(..)) && this(executor)")

      public Object auditOperation(ProceedingJoinPoint thisJoinPoint,

                  Object executor) {

            …

… aspect code

…

            }

 

However when I deploy the application in tomcat (with javaagent:aspectjweaver-1.6.1.jar option), I get a NPE which I have pasted below.

I also tried using aspectjweaver-1.6.4 version however got the same error.

 

Could somebody please point to any solution?

 

Thanks in advance,
