| === How can I suppress the Unexpected Exception dialog? |
| |
| If your code generates an uncaught exception at runtime or uses `Logger.log(Level l, String s, Throwable t)` with level => 900 (`Level.WARNING`), NetBeans will display a dialog box which can show the details of that exception to the user. |
| This is a welcome alternative to simply crashing the application, |
| and provided you have written solid code, |
| your user should never see this dialog anyway. |
| |
| But it is impossible to handle every possible exception or error, |
| and some developers might wish to simply suppress this dialog |
| so that the application neither crashes nor alerts the user that an uncaught exception/error was thrown. |
| You can do this by link:DevFaqPlatformRuntimeProperties.asciidoc[setting a system property at runtime] |
| named `netbeans.exception.report.min.level`. |
| The exact value of this property will depend on certain factors such as whether or not assertions are enabled, |
| but using a very high value such as `99999` should prevent the dialog from ever being shown automatically. |
| |
| The above on its own doesn't suppress the exception dialog entirely - the dialog will still be shown if the user clicks on the error icon. To suppress that too, set `netbeans.exception.alert.min.level` to a high value as well (i.e. `99999`). This means your users will not even know there was a problem, and will have no opportunity to find out (or report it) unless they scan their log file. |
