public class MarkShieldInputStream
extends ProxyInputStream
```
This is an alternative to ByteArrayInputStream which removes the synchronization overhead for non-concurrent access; as such this class is not thread-safe. Proxy stream that prevents the underlying input stream from being marked/reset.
This class is typically used in cases where an input stream that supports marking needs to be passed to a component that wants to explicitly mark the stream, but it is not desirable to allow marking of the stream.

2.8.0
