Funny, I didn't realize that this error was in there.
I don't remember this decision.

Any code that uses reflection will not work properly. This is a
problem because parts of the core class library depend on reflection.
For instance, character set translators and locales are loaded this
way.
You can work around this by explicitly linking in the ones you need,
but you need to know some internal details of libgcj to make this
work. We've talked occasionally of adding compiler options to make
this simpler, but nobody has done that yet.
It would be helpful if someone wrote a page for the gcc wiki about
static linking.
