When a
DataOutputStreaminstance wraps an underlyingByteArrayOutputStreaminstance,it is recommended to flush or close the
DataOutputStreambefore invoking the underlying instances's toByteArray(). Also, it is a good practice to call flush/close explicitly as mentioned for example here.This pull request adds a close method before calling toByteArray().
