USAGE of JAD

Does Java Decompiler guarantee 100% conversion from .class file to .java file.... It is normally said that the logic developed in .class file cannot be restored 100% to .java file..Is it so ?

In real time applications, .java files (source code is lost). Only .class files are available.....Is it advisable to retrieve source code from .class file and start developing the application.?
