SystemError (vaadin-all 7.7.46 API)

java.lang.Object
- com.vaadin.server.AbstractErrorMessage
- - com.vaadin.server.SystemError

All Implemented Interfaces:

ErrorMessage, Serializable
```
public class SystemError
extends AbstractErrorMessage
```
SystemError is an error message for a problem caused by error in system, not the user application code. The system error can contain technical information such as stack trace and exception. SystemError does not support HTML in error messages or stack traces. If HTML messages are required, use UserError or a custom implementation of ErrorMessage.
