Katalon 7.9.1 katalon fails working with web service and data files

Hi,
I find myself with a katalon problem in version 7.9.1 and it is that when working with variables in datafiles, when I have to pass them to the service to run it, it fails with the following error message:
java.lang.LinkageError: loader constraint violation: when resolving field “NODE”

I leave you in particular the case in which it fails.
String chasis = findTestData(‘Datos_Generales/ChasisYMotor’).getValue(‘CHASIS’, 1)

String motor = findTestData(‘Datos_Generales/ChasisYMotor’).getValue(‘MOTOR’, 1)
ResponseObject response = WS.sendRequest(findTestObject(‘Object Repository/WebSevices/Empadronamiento/VerificoEmp’,
[(‘chasis’) : chasis
, (‘motor’) : motor
, (‘gd’) : GlobalVariable.deloreanId
, (‘usuario’) : GlobalVariable.usuario]));
Y el error que lanza cuando se ejecuta eso es:
Root cause: java.lang.LinkageError: loader constraint violation: when resolving field “NODE” the class loader (instance of org/codehaus/groovy/tools/RootLoader) of the referring class, javax/xml/xpath/XPathConstants, and the class loader (instance of ) for the field’s resolved type, javax/xml/namespace/QName, have different Class objects for that type

Do you have any idea how to fix it?

Hi @mathiasduarte99,

@mathiasduarte99

The .classpath file contains this line:

This implies that this file was generated by Katalon Studio version 7.8.2.

On the other hand, you wrote:

I find myself with a katalon problem in version 7.9.1

The versions are mismatching.

Do you have any idea why this discrepancy occured?


Removing the <projectDir>/.classpath file may fix your problem. It will be automatically generated by Katalon Studio of your current version.

@kazurayam
I apologize, at that time I had the project open in version 7.8.2 to test if it worked in that version. And in fact in version 7.8.2 if it works the problem is found from that onwards.
Here is the .classpath with version 7.9.1

java.lang.LinkageError occurs when code is compiled with dependency version say v1 and then is running with dependency version say v2.

Possibly you once ran that project in Katalon Studio v7.8.2 successfully. Later you upgraded Katalon Studio to v7.9.2. Then the .groovy codes needs to be re-compiled in the KS v7.9.1, but you haven’t done it. Therefore java.lang.LinkageError occured. — This is what I guess.

How to fix?

  1. Stop Katalon Studio v7.9.1
  2. delete <projectDir>/.classpath file
  3. delete <projectDir>/bin directory
  4. delete <projectDir>/Libs directory
  5. restart Katalon Studio, open the project, and run it

This will force the .groovy codes to be cleanly re-compiled.

Hi, @kazurayam
I did the steps mentioned above but I still have the same problem.
Same mistake.
I deleted katalon, I downloaded it again, I deleted the .classpath and the two directories bin and libs.
Then I reopened katalon and the project but I still get the same error.

In my Katalon Studio 7.9.1 on Mac, I made a Test Case script

import javax.xml.xpath.XPathConstants
import javax.xml.namespace.QName

URL u1 = XPathConstants.class.getResource("/" + XPathConstants.class.getName().replaceAll("\\.", "/") + ".class");
System.out.println(u1);

URL u2 = QName.class.getResource("/" + QName.class.getName().replaceAll("\\.", "/") + ".class");
System.out.println(u2);

println XPathConstants.NODE

When I ran this, I got the following message:

This message tells me that javax.xml.namespace.QName class is loaded from jar:file:/Applications/Katalon%20Studio.app/Contents/Eclipse/configuration/resources/lib/stax-api-1.0.1.jar! file.

I believe that the QName class should not be loaded from stax-api-1.0.1,jar. It should be loaded from the rt.jar just as the XPathConstants class is loaded from the rt.jar. This is a bug mistakenly introduced in Katalon Studio 7.9.x.

-> @ThanhTo, @duyluong

Are you aware of this serious bug?


Once I enountered a similar issue as this. See


@mathiasduarte99

Please try removing the stax-api-1.0.1.jar out of your Katalon’s installation directory.

Could you move this topic into the Bug Reports category?

@kazurayam,
The solution of removing the stax-api-1.0.1.jar file from the directory installation was correct. Eliminating it was my problem.
Thanks for your help.
