Hi Andrew,
thanks, i changed it in the suggested way.
I've got one last question. I'm trying to capture the finalize calls of the
IO objects.
The pointcut(s) I use are these:
public pointcut writerFinalize() : call(void finalize())
&&(target(FileWriter)||target(PrintWriter));
public pointcut randomAccessFileFinalize() : call(void finalize())
&&target(RandomAccessFile);
public pointcut finalizeAll() : writerFinalize() ||
randomAccessFileFinalize() || ...
the advice:
after() : finalizeAll(){
System.err.println("finalize...");
close(thisJoinPoint.getTarget());
}
I added the JRE to the inpath
Again, the warning "advice has not been applied" occurs.
Changing the pointcuts into execution-pointcuts, the warning disappears,
although the advice isn't executed.
In addition, I tried to change the advice into before(): finalizeAll(),
without success.
Is there a possibility to capture finalize at all?
Or does the execution-pointcut apply and it is simply the VM that does not
call finalize?
