java error

[Warren Oyco]

I get the below error message when I go to the manage add on page.

java.util.concurrent.ExecutionException: java.lang.NullPointerException

[Guilherme V.]

Usually the culprit of your error can be found in the stack trace above the java.util.concurrent.ExecutionException: java.lang.NullPointerException.

Some of the most usual causes for null pointer exceptions on Confluence are described on this below article:

However, just like Nic stated, you'll need to analyse the application logs in order to identify what is in fact causing the issue. In case you need further assistance with this, I suggest you raise a support ticket at https://support.atlassian.com/

java.lang.NullPointerException is one of the most generic Java error messages you can get.

You'll need to read the application's log file to find the root cause of the error.
