    Description

      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.
