如何为任意一段java程序生成控制流图？

问题描述

我想直接从java源代码生成一个控制流图。我曾尝试使用 soot 生成控制流图，但 soot 会检查语法错误，如下所示。

D:\isoot>java -cp sootclasses-trunk-jar-with-dependencies.jar soot.tools.CFGViewer --soot-classpath .;"D:\isoot\Java\jre1.8.0_221\lib\rt.jar" --graph=BriefBlockGraph A -src-prec  java

我知道soot可以从.class文件生成控制流图，但是soot对java版本有严格的要求，即只能使用1.7版本的jdk，否则容易报错。这对我来说是致命的缺点，因为我有100个java项目在等待生成控制流图，只有1.7个jdk编译这些项目很困难。

我发现一些用于软件测试的软件可以很容易地直接从源代码中生成控制流图，例如visutin。这种软件是如何生成控制流图的？有没有开源代码？
