Method Details

handleError

public void handleError(Throwable e)

Handles arbitrary Throwables and completely terminates the JVM if it's an unrecoverable error, i.e. a VirtualMachineError. Use this method whenever catching a Throwable, before carrying on with your regular error handling.

Some example of VirtualMachineErrors include OutOfMemoryError, StackOverflowError and InternalError. We consider these errors unrecoverable because there is no action we can take to resolve them, and it is safer to terminate and let a hypervisor restart Zeebe.
