Confluence plugin Error opening URI [hazelcast] #33

Closed dfresh4130 closed 8 months ago

dfresh4130 commented 9 months ago

We just upgraded to Confluence 8.6.2 from 7.20.3 (data center edition). The javamelody plugin was updated to the latest version available of 1.95.0. When trying to access the /monitoring URI on confluence like normal we get a 500 error. The Confluence logs show the below error. This appears to be similar to this issue for bitbucket.

I will transfer this issue in the jira-confluence-javamelody repository

This issue is caused by the presence of hazelcast 3.12.13 and of xalan 2.7.3 in Confluence 8.6.2 and by the fix for the hazelcast issue https://github.com/hazelcast/hazelcast/issues/20928. I have added a catch to log a warning instead of throwing an exception.

If you don't want a warning each time the monitoring page is displayed, you can set a system property -Dhazelcast.ignoreXxeProtectionFailures=true or you can complain to Hazelcast or Atlassian about Xalan 2.7.3.
