This means that the pointcut for the advice did not match, and it should be debugged as described in Debugging Pointcuts.
You can use META-INF/aop.xml
to control which
messages are produced during LTW. The following example will produce
basic informational messages about the lifecyle of the weaver in
addition to any warning or error messages.
<aspectj> <weaver options="-verbose"> </weaver> </aspectj>
The messages indicate which META-INF/aop.xml
configurations file(s) are being used. Each message is also preceeded by the
name of the defining class loader associated with weaver. You can use this
information in a large system to distinguish between different applications each
of which will typically have its own class loader.

It is often difficult to determine, especially when using load-time weaving (LTW),
why advice has not been woven. Here is a quick guide to the messages to
look for. Firstly if you use the -verbose
option you
should see the following message when your aspect is registered:
info register aspect MyAspect
Secondly if you use the -debug
option you should
see a message indicating that you class is being woven:
debug weaving 'HelloWorld'
However this does not mean that advice has actually been woven into
your class; it says that the class has been passed to the weaver. To determine
whether your pointcuts match you can use the -showWeaveInfo
option which will cause a message to be issued each time a join point is woven:
weaveinfo Join point 'method-execution(void HelloWorld.main(java.lang.String[]))' ...
If advice is woven at this join point you should get the corresponding message.
