Hi,
I am not an expert of javap analysis.
I try to join the whole trace.
I think you are right. decompiling the TestingClass with JD-GUI,
doesn't show any line number.
has i made something wrong, at compilation time ?
extract of javap -verbose TestingClass :

Hi,
Can you confirm if the code you are load time weaving into has line
number table entries? Use javap with -verbose to see them if they are
there, look for one attached to each method. If they are missing
that explains it, if they are not missing it seems like a bug.
cheers,
Andy

Hi,
withAspectJ Compiler 1.7.1 (DEVELOPMENT - Built: Wednesday Oct
24, 2012 at 18:06:22 GMT) and LTW,
the call
thisJoinPoint.getStaticPart().getSourceLocation().getLine()
always returns 0
My advice is an around advice. I test if( null !=
thisJoinPoint.getStaticPart().getSourceLocation())
The pointcut is correctly weaved, and the advice excecutes
correctly ( except for retrieving the noLine)
How can we explain this? a bug ?
I give below the code to test ( my tests give always a
getLine() =0) :
The Class :
package jlp.aspectj.test;
import java.util.HashMap;
public class TestingClass implements Runnable {
private String name = "";
public boolean running = true;
private int limit = 1000000;
Thread thread = new Thread(this);
public String getName() {
return name;
}
public void setName(String name) {
this.name <http://this.name> = name;
}
public TestingClass(String name, int limit) {
this.name <http://this.name> = name;
this.limit = limit;
}
public TestingClass(String name) {
this.name <http://this.name> = name;
}
public TestingClass() {
this("no_name");
}
public void myShortMethod() {
System.out.println("I will sleep for 100 ms");
try {
Thread.sleep(100);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void myLongMethod() {
System.out.println("I will sleep for 1s");
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void myStressingMethod(int limit) {
HashMap<String, Integer> hm = new HashMap<String,
Integer>();
System.out.println("Entering in myStressingMethod
limit=" + limit);
for (int i = 0; i < limit; i++) {
hm.put(new Integer(i % 100).toString(), new
Integer(i % 1000));
}
hm.clear();
}
public void run() {
while (running) {
myShortMethod();
myStressingMethod(limit);
myLongMethod();
}
}
public static void main(String[] args) {
// TODO Auto-generated method stub
TestingClass[] tabRunners = new
TestingClass[Integer.parseInt(args[0])];
for (int i = 0; i < tabRunners.length; i++) {
tabRunners[i] = new TestingClass("thread_" + i,
Integer.parseInt(args[1]));
tabRunners[i].thread.start();
}
}
}
The AspectJ to (LTW) weave :
package jlp.perf.aspects.concreteAspects;
public aspect ConcreteTester {
public pointcut methods():execution(public * *..*.*(..));
Object around() : methods()
{
Object ret = proceed();
String str="Aspect ConcreteTester
:"+thisJoinPointStaticPart.getSignature().getDeclaringTypeName()+"."+
thisJoinPointStaticPart.getSignature().getName()+";"+thisJoinPointStaticPart
.getSourceLocation().getLine();
System.out.println(str);
return ret;
}
}
