Likewise, I'm curious about whether it would be possible to let Javassist accept Java 5 code forms like boxing and unboxing and handling of generics correctly in code snippets in source. For example, I tried to extend abstract class Holder { T get(); } I have to implement that with casts and Object get(); to work and I can't, for example, return an int and have it boxed to be an Integer as I could in Java 5 source. Is there any plan to extend Javassist in this way? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4019026#...
