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<https://commons.apache.org/proper/commons-io/javadocs/api-release/index.html>
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]
see also: org\testng\shaded\com\google\gson\stream\JsonReader.java:1295::0
How can I get rid of this warning?
