XmlBeans.NO_TYPE initialized not correctly

• Key: XMLBEANS-285
• Type: Bug
• Status: Open
• Priority: Major
• Assignee: Radu Preotiuc-Pietro
• Reporter: Valery Gorbunov
• Component/s: XmlObject
• Affects Version/s: Version 2.2.1

Description

XmlBeans.NO_TYPE initialized not correctly if working with XmbBeans begins with
org.apache.xmlbeans.impl.schema.BuiltinSchemaTypeSystem class.
Test cases:

Correct initialization:
package mypackage;

import junit.framework.TestCase;

import org.apache.xmlbeans.XmlBeans;
import org.apache.xmlbeans.impl.schema.BuiltinSchemaTypeSystem;


public class XMLTest extends TestCase{

public XMLTest() {
super();
}
public XMLTest(String name) {
super(name);
}
public void test2(){
assertNotNull(XmlBeans.NO_TYPE);
assertNotNull(BuiltinSchemaTypeSystem.ST_NO_TYPE);
}
}

Incorrect initialization.

package mypackage;

import junit.framework.TestCase;

import org.apache.xmlbeans.XmlBeans;
import org.apache.xmlbeans.impl.schema.BuiltinSchemaTypeSystem;


public class XMLTestWithFail extends TestCase{
public XMLTestWithFail() {
super();
}
public XMLTestWithFail(String name) {
super(name);
}

public void test(){
BuiltinSchemaTypeSystem.get();
assertNotNull(XmlBeans.NO_TYPE);
}
}

Comments

Very interesting observation. This is because BuiltinSchemaTypeSystem and XmlBeans circularily depend on one another in their static initializers, which is a bad idea. We need to fix this.
