code-ferry opened a new pull request #327:
URL: https://github.com/apache/commons-io/pull/327
The currentBufferIndex means the index of the current buffer in the class
AbstractByteArrayOutputStream.
when creating new buffer first time and the write size , currentBufferIndex
should not change.
Luckily, this mistable does not affect any public methods and the result.
After my modification, all the unit tests also pass.
```
@Test
public void testCurrentBufferIndex() throws IOException,
IllegalAccessException, InstantiationException, NoSuchFieldException {
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
outputStream.write(new byte[]{0x31, 0x32});
// Get Field currentBufferIndex
Field field =
ByteArrayOutputStream.class.getSuperclass().getDeclaredField("currentBufferIndex");
field.setAccessible(true);
int currentBufferIndex = (int) field.get(outputStream);
// print 1. I think the right value is 0.
//
// Only 2 bytes are written, less than the default value 1024.
// The size of array buffers is only 1, and currentBufferIndex
should be 0.
System.out.println(currentBufferIndex);
}
```
