The addition of the method breaks the contract with existing alternative implementations of IProvisioningAgent. By making the method a default method the contract can be fulfilled. This also makes the implementation in class ProvisioningAgent obsolete. Update version of bundle org.eclipse.equinox.p2.core for 4.14.
