I updated a number of plugins and one of them froze Confluence. I have tried restarting the service a few times even in safe mode and even rebooted the server but no much luck. I am getting three errors that I have never seen before and Googling these is not yielding any fruits. Any assistance on these three errors?
First 2 are from the confluence log, last one is from catalina startup

the 'setErrorHandler' method to fix this.

Hi Paul,
if it's a production instance, I'd recommend contacting Atlassian Support
Perhaps you could try clearing the plugin cache, have a look at Confluence Startup Problems Troubleshooting as well.
Thanks for the tip, I had cleared out the cache folders as the first solution. However, I have managed to get it back up and running. The problem is that it took about 30 minutes to start up.

Glad you're up and running again, Paul. That sure is a long boot time, might be worth investigating it further.
Have a nice day.
