It's possible to specify an action to take for any exit code by making use of the wrapper.on_exit.default property and setting it to either SHUTDOWN or RESTART. The default value is SHUTDOWN.

The action can be one of the following:

• RESTART
• SHUTDOWN

wrapper.on_exit.default=SHUTDOWN

In addition, it is possible to specify what will happen for a specific exit code by defining a property whose name is wrapper.on_exit. followed by the exit code.

The property name starts with wrapper.on_exit.<n>. and the "<n>" component of the property name is an exit code. wrapper.ignore_sequence_gaps property can optionally be set to allow gaps in the sequence.

The action can be one of the following:

• RESTART - will launch a new JVM.
• SHUTDOWN - will proceed to shutdown the Wrapper.
• PAUSE (ver. 3.5.0 or later) - will put the the Wrapper into a paused state. This delays the restart of the JVM until the Wrapper is resumed. If Wrapper's pausing is not enabled then the JVM will be restart as if the RESTART action was configured. See the wrapper.pausable property for details.

If an on_exit.<n> property is not defined for a given exit code, then it will default to the value of the wrapper.on_exit.default property.

wrapper.on_exit.1=RESTART

To configure the Wrapper to restart the JVM for all exit codes except the exit code "0" (zero), use the following:

wrapper.on_exit.default=RESTART
wrapper.on_exit.0=SHUTDOWN

on_exit properties will be triggered by calls to WrapperManager.stop(n), WrapperManager.stopImmediate(n), and System.exit(n).

External signals or actions which trigger the shutdown of the Wrapper and its JVM will cause these properties to be ignored as the Wrapper is shutting down. This means configuring the Wrapper to restart on any exit code will not prevent the Wrapper from shutting down.
