With JITServer Technology, each client JVM has a unique ID that is generated during JVM bootstrap. When checkpointing a JVM that is supposed to be used in client mode, this client UID gets baked into the JVM snapshot, and all JVM processes that are restored from this snapshot will have the same UID, which confuses the server. This comit re-generates the client UID during the snapshot restore operation so that different clients will have different UIDs.
