Description

The org.crac is designed to provide smooth CRaC adoption. Users of the library can build against and use CRaC API on Java runtimes with jdk.crac, javax.crac, or without any implementation.

  • In compile-time, org.crac package totally mirrors jdk.crac and javax.crac.
  • In runtime, org.crac uses reflection to detect CRaC implementation. If the one is available, all requests to org.crac are passed to the implementation. Otherwise, requests are forwarded to a dummy implementation.

The dummy implementation allows an application to run but not to use CRaC:

  • resources can be registered for notification,
  • checkpoint request fails with an exception.
