Eclipse class files not updating
This means that source files written to use Eclipse SDK 4.5 APIs might successfully compile and run against Eclipse SDK 4.6 APIs, although this is not guaranteed. If source files use new Eclipse SDK APIs, they will not be usable with an earlier version of the Eclipse SDK.
JD-GUI is a standalone graphical utility that displays Java source codes of “.class” files.You can browse the reconstructed source code with the JD-GUI for instant access to methods and fields. It allows you to display all the Java sources during your debugging process, even if you do not have them all.JD-Core is a library that reconstructs Java source code from one or more “.class” files.Programs that use affected APIs and extension points will need to be ported to Eclipse SDK 4.6 APIs. There is no guarantee that compliance with Eclipse SDK 4.6 APIs would ensure compliance with Eclipse SDK 4.5 APIs.Refer to for a discussion of the kinds of API changes that maintain contract compatibility.
