String literals can only be allocated statically if you do link-time
merging (since Strings have to be interned).  This is difficult
when doing dynamic linking, but should be straight-forward when
satic linking.

Yes, those can be statically allocated.  The advantage is biggest for
arrays, but even non-arrays can win if you can "inline" some of the
initialization as initialized static data.

Currently gcj does not do this, but it is planned.
