RE: [aspectj-users] No warning for class not found in parameter type
|
I wonder if something could be done in AJDT to highlight
things, such as a decoration for libs, packages and classes to indicate which
are and aren't on the inpath.
I can't see this working unless the inpath projects were
all AJDT enabled, which is something I try to avoid.
This is something that would be easier to browse in the
Problems/Markers view once the Info messages have accurate resource/line number
info.

Hi Kevin,
So there were classes with the join points in on
the classpath that needed promoting to the inpath? To put out a warning,
wouldn't AspectJ have had to completely analyse everything on the classpath
for potential join points to see if this kind of mistake had been made?
That would be rather expensive I think. I guess that is one reason why
the inpath exists in the first place, so that we don't analyse/weave more
classes than necessary. I can see it was awkward to debug for you, I'm
just having trouble working out what AspectJ could do better that wouldn't
kill performance.
cheers,
Andy.

I
just spent hours tracking down a problem which turned out to be a
peculiarity in AspectJ. I have a pointcut
pointcut setter(PropertyChangeSupported b): execution(void set*(*))
&& this(b);
which I use to pick out setters of a bean. The
advice that uses this pointcut was not being applied when the parameter to
the method was a non-primitive type. After much investigation I determined
that the classes at issue were not specified in the inpath; adding them
solved the problem. I use a tightly controlled inpath to minimize the amount
of time that the AspectJ compiler spends when running. The behavior of
simply ignoring those methods was very unexpected to me; it seems that some
sort of warning should have been issued.
Thoughts?
