NonFatal

scala.util.control.NonFatal

Extractor of non-fatal Throwables. Will not match fatal errors like VirtualMachineError (for example, OutOfMemoryError and StackOverflowError, subclasses of VirtualMachineError), ThreadDeath, LinkageError, InterruptedException, ControlThrowable.

Note that scala.util.control.ControlThrowable, an internal Throwable, is not matched by NonFatal (and would therefore be thrown).

For example, all harmless Throwables can be caught by:

try {
  // dangerous stuff
} catch {
  case NonFatal(e) => log.error(e, "Something not that bad.")
 // or
  case e if NonFatal(e) => log.error(e, "Something not that bad.")
}
