Ok, I after a detour finally got on this and tried to make it work. You were
right, I can actually go with compile-time weaving. For those who struggle:
1. Eclipse needs a lot more RAM if it has to go through rt.jar (located in
the jre)
2. The setting to add -injars is in Properties/AspectJ
Compiler/Other/non-standard compiler option, something like:
-injars :/usr/lib/jvm/java-6-sun-1.6.0.16/jre/lib/rt.jar
But now I'm a bit irritated by my result: First off, I get a 24 MB jar,
which is rather big, considering I only weave this:
before(JComponent component):
execution( public String JComponent.getToolTipText(MouseEvent) )
&& target(component) {...}
It also spans into strange directories, such as com.sun.corba (do they
really use swing's tooltips? I doubt it). I assumed I could just add the
created jar as a library into my project, but that does not have any effect
(but the non-aspect classes in that jar are visible and usable just fine).
Any ideas?
Thanks
