[Mingw-users] Question about GCJ

[Me M. a. I <sta...@li...>]

I try to compile a class with annotated methods, for example,
and GCJ warns me that it can't find

java.util.concurrent.Future

class, and doesn't understand the @ annotation symbol.

I can do without using annotations at all, however is there a .jar
file or class file to solve this problem, and have annotations
compile fine?  Is there a URL link to such a file?
