The previous behavior can be re-enabled after due consideration of any impact by setting the runtime property sun.rmi.server.disableIncomingHttp to false.

Users can still add individual named curves to disabledAlgorithms properties separate from this new property. No other properties can be included in the disabledAlgorithms properties.

From this release, the RMI property java.rmi.server.useCodebaseOnly is set to true by default.
