FailureHandler (Hibernate Search Engine 6.1.3.Final API)

```
public interface FailureHandler
```
A handler for failures occurring during background operations, which may not have been reported to the caller due to being executed asynchronously.
The handler should be used to report failures to application maintainers. The default failure handler simply logs failures at the ERROR level, but it can be replaced with a custom implementations through a configuration property.
Handlers can be called from multiple threads simultaneously: implementations must be thread-safe.

```
void handle(FailureContext context)
```
    Handle a generic failure.
