StackOverflow due to ToStringBuilder
Summary: StackOverflow due to ToStringBuilder
Product: Commons
Version: 1.0 Alpha
Platform: Other
OS/Version: Other
Status: NEW
Severity: Normal
Priority: Other
Component: Lang
AssignedTo: commons-dev@jakarta.apache.org
ReportedBy: keeskuip@technologist.com
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());
}
}
