    @GreeshmaVSNair "stackoverflow is a platform to help each other" close but not entirely correct. New people often are misunderstanding goal of this site. They think we are here to help them specifically. That is NOT the truth. This site was created to be repository of programming questions and answers which can help many people, not just asker. Helping asker is additional effect, but because of that misconception askers incorrectly think that they are entitled to get answers for any programming question just because it is about programming, regardless of its quality.

See here : Compatibility Guide for JDK 8 .



Among the Incompatibilities between Java SE 8 and Java SE 7 :




In previous releases, some implementations of
Collection.removeAll(Collection) and retainAll(Collection) would
silently ignore a null parameter if the collection itself was empty.
As of this release, collections will consistently throw a
NullPointerException if null is provided as a parameter.




So your program could simply contain :



    List<String> list = new ArrayList<>();



    list.removeAll(null);


It will work in Java 7 , not in Java 8 .



This is one example, if you get through the above link, you will find several other ways to have such an incompatible program.

            A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

            Image
            0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
