Description

The ToStringBuilder doesn't handle relations to other objects
very well. It's very easy to get into an never-ending-loop.
The following code will crash the JVM with a StackOverflowError :

import org.apache.commons.lang.builder.ToStringBuilder;

public class Test1
{
Test1 test;

public Test1() {}

public void setTest(Test1 test)

{ this.test = test; }

public String toString()

{ return ToStringBuilder.reflectionToString(this); }

public static void main(String[] args)

{ Test1 test1; Test1 test2; test1 = new Test1(); test2 = new Test1(); test1.setTest(test2); test2.setTest(test1); System.out.println(test1.toString()); }

}
