This is a possibility, but it might not be enough. Indeed, this just hide the
exception thrown by ASM with this IOException.
I dont' have a good answer for now about this issue. Ignoring (writing a
warning) when reading an empty class is a possibility,
however, this may not be the adequate behavior.
What I don't really get, is why the compiler generates this empty class file.
Is this a synchronization issue (the file is created, but the
compilation is not yet done). If you have more details about that, we can
probably find a good way to manage this case.

Clement
