PVS-Studio static analyzer team, which until recently was searching for bugs and potential vulnerabilities only in C, C++, and C# code, has prepared a new version of their tool for Java code as well. Despite the fact that in the Java world there is already a number of static analysis tools, developers believe that their analyzer can be powerful and will be a good competition.
One of developers wrote in his article about the way how PVS-Studio for Java was created. First of all, it was necessary to figure out the development process of a syntax tree and semantic model. As these elements are basic, static analyzer is built around them. In addition to them, the analyzer also requires data flow analysis, which enables you to calculate the possible values of variables and expressions in each point of the program and, thanks to that, find errors. Also the analyzer needs the annotation mechanism, diagnostic rules, integration, testing, and other techniques, explained in detail in the article.
Traditionally, the author gave examples of errors from different open source projects, that the Java analyzer has detected. The author also noted that in the future articles with a more detailed report on each project will be available. So far you can review errors from the Hibernate, Hive, JavaParser, Jenkins projects and several others.
Besides that, when the first alpha version of the Java analyzer is available, developers suggest participating in its testing for those who would like to. To do this, write to their support and they will contact you.
