Hello All - We have an issue with loading the classic UI pages in our environment and this happens all of a sudden. We see the following errors in the console logs. The page is not loading properly. I see some blank spaces between the contents of the page. Can someone tell me what could be the cause for this issue? This is happening in AEM 6.5

Hey @aemninja please try restarting the instance. Also please let me know if you're seeing this in your error log:

try these steps and see if this works:

  1. Stop the AEM instance. Go to <aem-installation-directory>/ crx-quickstart/conf and open the sling.properties file.
  2. Search for org.osgi.framework.bootdelegation= . Add jdk.internal.reflect,jdk.internal.reflect.* properties to display the result as:
    bilala23933647_0-1616135403789.jpeg
  3. Save the file and restart the AEM instance.

 

Thanks,

Bilal.

@bilal_ahmad - Even after the restart, I still see the same issue and also I don't see any errors that you specified in the log
