Reproducable example of bug:

MyExample.java
==============

package demos.digesterbug;

import org.apache.commons.digester.Digester;
import org.xml.sax.SAXException;
import demos.MyTag;

import java.io.File;
import java.io.IOException;

public class MyExample {

    public MyExample() {
        digesterBugTest();
    }

    public static void main(String[] args) {
        new MyExample();
    }

    private void digesterBugTest(){
        Digester digester = new Digester();
        digester.setValidating(false);

        digester.addObjectCreate("root/tag", MyTag.class );

        digester.addSetProperties("root/tag","attrib", "attrib" );

        digester.addCallMethod("root/tag",  "setBody", 0);

        try {

            MyTag abp = (MyTag) digester.parse(new File("digesterTest.xml"));

            System.out.println("abp.getBody() = " + abp.getBody());
            System.out.println("abp.getAttrib() = " + abp.getAttrib());
            String verify = "Line one followed by two newlines.\n\nLine two
followed by two newlines.\n\nLast Line.";
            System.out.println("Confirm a normal string works = " + verify);

        } catch (IOException e) {
            e.printStackTrace();
        } catch (SAXException e) {
            e.printStackTrace();
        }
    }
}

MyTag.java
==========
package demos.digesterbug;

public class MyTag {
    private String attrib;
    private String body;

    public String getAttrib() {
        return attrib;
    }

    public void setAttrib(String attrib) {
        this.attrib = attrib;
    }

    public String getBody() {
        return body;
    }

    public void setBody(String body) {
        this.body = body;
    }

}


digesterTest.xml
================
<?xml version="1.0" encoding="utf-8"?>
<root>
<tag attrib="Line one followed by two newlines.\n\nLine two followed by two
newlines.\n\nLast Line.">
Line one followed by two newlines.\n\nLine two followed by two newlines.\n\nLast
Line.
</tag>
</root>

Example of output
=================
abp.getBody() = Line one followed by two newlines.\n\nLine two followed by two
newlines.\n\nLast Line.
abp.getAttrib() = Line one followed by two newlines.\n\nLine two followed by two
newlines.\n\nLast Line.
Confirm a normal string works = Line one followed by two newlines.

Line two followed by two newlines.

Last Line.
