["Ted Lundqvist (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-10530?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ted Lundqvist updated GROOVY-10530:
-----------------------------------
    Description: 
Calling firstChild returns a Boolean with the value false but getFirstChild() returns the correct object.

Noticed this problem when upgrading from Groovy 3.0.5 to 4.0.0
{code:java}
import org.junit.jupiter.api.Test
import org.w3c.dom.Node
import org.xml.sax.InputSource

import javax.xml.parsers.DocumentBuilderFactory

import static org.junit.jupiter.api.Assertions.assertEquals

class XmlTest {
    @Test()
    void firstChild_test() {

        String xml = "<xml><foo>bar</foo></xml>"
        Node node = DocumentBuilderFactory.newInstance()
                .newDocumentBuilder()
                .parse(new InputSource(new StringReader(xml)))

        assertEquals(node.getFirstChild().class, node.firstChild.class)
        //org.opentest4j.AssertionFailedError: 
        //Expected :class com.sun.org.apache.xerces.internal.dom.DeferredElementImpl
        //Actual   :class java.lang.Boolean
    }
}
{code}
