the class ByteBufferTest method testLargeInsertion.

@Test
public void testLargeInsertion() {
    BufferManager buf = new BufferManager();
    IonBinary.Writer writer = buf.openWriter();
    // Write enough data to overflow the first block
    byte[] initialData = new byte[BlockedBuffer._defaultBlockSizeMin + 5];
    // Now insert lots of stuff at the beginning
    try {
        writer.write(initialData, 0, initialData.length);
        writer.setPosition(0);
        writer.insert(5000);
    } catch (IOException e) {
        throw new IonException(e);
