Re: Re :[aspectj-users] aspect on a java API class

Weaving of java. and javax. types has been discussed on the list
recently.  You need an up to date AspectJ and you need to use a weaver
option to force it to weave those types in addition to normal
configuration info.  The Javax one is shown below, the
weaveJavaPackages=true option is what you need.
