Confluence plugin Error opening URI [hazelcast] #33

Closed dfresh4130 closed 10 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.
