>
> ResizableDoubleArray has several synchronised methods, but is not
> thread-safe, because class variables are not always accessed using the lock.
> Is the class supposed to be thread-safe?
> If so, all accesses (read and write) need to be synch.
> If not, the synch. qualifiers could be dropped.
> In any case, the protected fields need to be made private.
