Out of curiosity, is there any way to determine the size of the
interned strings now that they are no longer in PermGen? I assume that
since 6962931 [1] with interned strings moving to the regular heap
there isn't any way to compute the size of interned strings other than
through a heap dump where they would show up like any other String,
but I'd just like to confirm.

Thanks,
Dave
