[seam-dev] First cab off the rank!

[Stuart Douglas]

I have done up a quick and dirty one using JDK proxies, that seems to work ok (all my XML config tests pass and most of the code was stolen from AnnotationLiteral).

The class that creates the proxy:

http://bazaar.launchpad.net/~stuart-baileyroberts/jbraze/trunk/annotate/head%3A/spi-tools/src/main/java/org/jbraze/spitools/AnnotationCache.java

The InvocationHandler:

http://bazaar.launchpad.net/~stuart-baileyroberts/jbraze/trunk/annotate/head%3A/spi-tools/src/main/java/org/jbraze/spitools/AnnotationInvocationHandler.java

To create an instance you go 

AnnotationCache.getAnnotation(MyAnnotation.class,memberValues);

where memberValues is a <String,Object> map of the annotations member values.
