Issue Description

When attempting to update from 5.4.16 to 5.4.17 the update process will hang on the loading bar on screen. Closer inspection of the logs reveals that nothing is happening during this time.

IMPORTANT: This issue is difficult to reproduce. We've tried to reproduce multiple times, in multiple ways. I finally managed to reproduce the issue in one of our demonstration environments.

Steps to Reproduce

1. Navigate to the "Manage Add-ons" menu
2. Click the update button

Expected Outcome

The update should display the progress bar and complete within 1-2 mins

Actual Outcome

The update progresses slowly through the progress bar until it eventually appears to get stuck. Once in this state, it stays this way until someone restarts the instance.

Versions

Confluence 6.10.1, 6.7.2

ScriptRunner 5.4.16

Workarounds

There are known workaround for this issue:

• Disable any ScriptRunner dependent plugins that you might have installed and re-try the update.
• If the above does not work you can uninstall ScriptRunner and then install the new version from scratch.
