Method

ByteBufferexpand(ByteBuffer bb, int minSize, int maxSize)
Ensure that specified buffer has at least enough capacity to accommodate 'minSize' additional bytes, but not more than 'maxSize' additional bytes. 
if (maxSize != -1 && maxSize < minSize) {
    throw new IllegalArgumentException("maxSize < minSize");
if (bb == null) {
    int size = Math.max(minSize, INITIAL_CAPACITY);
    if (maxSize != -1 && size > maxSize)
        size = maxSize;
    return ByteBuffer.allocate(size);
...
ByteBufferexpandBuffer(ByteBuffer existingBuffer, int additionalRequired)
expand Buffer 
int pos = existingBuffer.position();
if ((pos + additionalRequired) > existingBuffer.limit()) {
    if ((pos + additionalRequired) < existingBuffer.capacity()) {
        existingBuffer.limit(pos + additionalRequired);
    } else {
        int newCapacity = existingBuffer.capacity() + additionalRequired;
        java.nio.ByteBuffer newBuffer = java.nio.ByteBuffer.allocate(newCapacity);
        existingBuffer.flip();
