Re: [aspectj-users] Why Aspectj is weaving excluded packages
Can you turn off the security manager temporarily to see what the exception is that it is trying to dump?

Thanks Andy,
 
I did the code change accordingly, here is the changed code. I tested the aspectj accordingly.
 
 pointcut apppackage(): within(com.tcs..*);
 pointcut thirdpartypack():execution(* com.ibm..*(..));
 pointcut seperate(): !within(com.ibm..*);
 pointcut UtilMethods() :  apppackage() && (call( * java.util..add(..)) || call( * java.util.Map..put(..))) && !myclass() && !cflow(thirdpartypack()) && seperate();
 
 
Then the following AccessControl Permission is coming from the websphere7 application server. Here is the error trace.

Subject: Re: [aspectj-users] Why Aspectj is weaving excluded packages


It is trying to weave com.ibm.db2.jcc.b.kc because it contains calls to add or put. Cflow is implemented by inserting a check at the joinpoint of interest which does the check as to whether we are actually in the specified control flow.  Your code might be in com.tcs..* but maybe you use code in com.ibm.db2.jcc.b.kc (we don't know) - that would mean calls made from add/put are in the control flow of your code.

Unfortunately com.ibm.db2.jcc.b.kc looks to be near some size limits for bytecode and is dangerous to weave because the limits will get blown. I would add a !within(com.ibm.db2.jcc.b.kc) to your pointcut to skip that class.

If you are only interested in calls made from code within com.tcs..* and not from any transitively invoked code you could skip cflow and use within(com.tcs..*)

Hi ,
 
I specified weaving as follows in the code
 
pointcut myclass() : within(HeapAspect);
pointcut apppackage(): execution (* com.tcs..*(..));
pointcut UtilMethods() : cflow(apppackage()) && (call( * java.util..add(..)) || call( * java.util.Map..put(..))) && !myclass();
But it is trying to weave the com.ibm package as well. Is there a solution for this.
