To reproduce this issue:
- Assume the platform is on Liferay DXP 7.0 SP6 (Fix Pack 32) or older.
- Shut down the application server before patching the platform.
- Download Liferay DXP 7.0 Fix Pack 37 or higher.
- Follow the instructions for Patching DXP 7.0 Source Code.
- Start the application server again once the new fix pack has been applied. (For testing purposes, Fix Pack 39 was used.)
Resolution
Staus: Fixed
Update to Fix Pack 42 or higher.
The latest fix packs are available for download here: Download DXP Fix Packs
For subscribers who have not yet updated to Fix Pack 42 or higher, Liferay Technical Support has provided the following Groovy script. This can be executed from the Control Panel → Configuration → Server Administration.
- Navigate to the Control Panel → Configuration → Server Administration.
- Click on the Script tab.
- Select Groovy from the Language dropdown.
- Paste the script in the text area.
import com.liferay.portal.kernel.model.ClassName;
import com.liferay.portal.kernel.service.ClassNameLocalServiceUtil;
String newClassName = "com.liferay.rss.web.internal.util.RSSFeed";
ClassName className = ClassNameLocalServiceUtil.getClassName(newClassName);
ClassNameLocalServiceUtil.deleteClassName(className); - Click the Execute button.
- Verify the success message displays.
The changes will not be applied immediately and instead will be applied the next time the application server is started. At this time, the error message will not appear. The permanent resolution remains to apply the latest Fix Pack (42 or higher).
