# Register mechanism is no longer required for local / exit span
|
|
|
|
Since version 6.6.0, SkyWalking has removed the local and exit span registers. If an old java agent (before 6.6.0) is still running,
|
|
which registers to the 6.6.0+ backend, you will face the following warning message.
|
|
```
|
|
class=RegisterServiceHandler, message = Unexpected endpoint register, endpoint isn't detected from server side.
|
|
```
|
|
|
|
This will not harm the backend or cause any issues, but serves as a reminder that your agent or other clients should follow the new protocol
|
|
requirements.
|
|
|
|
You could simply use `log4j2.xml` to filter this warning message out.
