RMI Registry Issue
A bug in the rmiregistry command included in this release may cause unintended exceptions to be thrown when an RMI server attempts to bind an exported object which includes codebase annotations using the "file:" URL scheme. The RMI servers most likely to be effected are those which are invoked only by RMI clients executing on the same host as the server.
RMI annotates codebase information as part of the serialized state of a remote object reference to assist RMI clients in loading the required classes and interfaces associated with the object at runtime. Exported objects which are looked up in the RMI registry and invoked by RMI clients running on hosts other than the server are usually annotated with codebase URL schemes, such as "http:" or "ftp:" and these should continue to work correctly.
As a workaround, RMI servers can set the java.rmi.server.codebase property to use codebase URLs other than the "file:" scheme for the objects they export.
