Sure looks that way, doesn't it?
Hmm, that line predates the import into the public gcc tree.
At this point, probably no-one knows what was intended here.

What happens when you change this to static?
Perhaps we're supposed to read java.lang for each file.  That makes
sense in a way... but then, I've never really read through the import
handling code.
