[jbosstools-dev] Seam Scanner for class files

> JDT does not include annotations into java model.

true, but that is why you use something like APT does and reads the 
annotations. e.g. use the compilation participant and parse the source
and you can visit the nodes. I did that in my initial prototype, 
unfortunatly i don't have the code on my laptop. I'll post it when I 
find it or get back to my desktop.

I don't think loading the classes is a sustainable usage since 
classfiles will not be available when incomplete files and is it not 
inefficient and impossible to clean up.

For .jar's it's usable to look into ClassFileREader thouhgh.
