Ick. This sort of failure happens all too often on targets without weak
pointer support.
Did you perhaps build libjava without optimization (i.e. CPPFLAGS = -g)?
Sometimes that causes methods that would otherwise be inlined to be
generated instead. (Even so, the "#pragma interface" directive in
header files ought to prevent that.)
