[aspectj-users] TypePatternsAspect.aj:5::0 does not match because declar

[Mikael Petterson <mikaelpetterson@xxxxxxxxxxx>]

I have a testcase (TESTNG) looking like this:

public class Example4 {

 @Test

  public void testCallToReadMethods() throws IOException {

      NullReader nullReader = new NullReader(10);

      nullReader.read();

      char[] chars ={ 'a', 'b', 'c', 'd', 'e' };

      nullReader.read(chars);

      nullReader.close();

     

  }

}

It calls methods in apache commons-io:

https://commons.apache.org/proper/commons-io/javadocs/api-release/index.html

Apache Commons IO 2.6 API

This package provides a component for monitoring file system events (directory and file create, update and delete events).

commons.apache.org

This is my simple aspect:

public aspect TypePatternsAspect {

   

    pointcut read(): call(* org.apache.commons.io.input.NullReader.read(..));

   

    before() : read() {

        String callingClass = thisJoinPoint.getStaticPart().getSourceLocation().getWithinType().getName();
        System.out.println("Caller "+callingClass);

    }

   

}

I can see that print is done 3 times:

Caller examples.Example4

Caller examples.Example4

Caller org.apache.commons.io.input.NullReader

Questions:

1. Does this mean that one of these reader methods call another read() within NullReader?
2. Looking at the log below I wonder:
   a) Why is AspectJ Weaver called twice?
   b) What does this warning mean:
   
   
   [AppClassLoader@18b4aac2] warning at examples\C:\Users\eraonel\git\java-runtime-stats\collector\src\test\java\examples\TypePatternsAspect.aj:5::0 does not match because declaring type is java.io.Reader, if match desired use target(org.apache.commons.io.input.NullReader) [Xlint:unmatchedSuperTypeInCall]

   How can I get rid of this warning?
