at com.confluence.page.tracking.services.PageEventListener.handlePageRemoveEvent(PageEventListener.java:154)The stack trace includes classes from the third-party app: com.confluence.page.tracking.services.PageEventListener.handlePageRemoveEvent which is part of Page Views plugin by EliteSoft.
The issue was discovered with version 2.5.0 for Page Views plugin:
<plugin>
<key>com.elitesoftsp.confluence.page.tracking.plugins</key>
<name>Page Views</name>
<version>2.5.0</version>
<vendor>EliteSoft</vendor>
<status>ENABLED</status>
<vendor-url>https://elitesoftware.atlassian.net/wiki/spaces/PV/overview</vendor-url>
<framework-version>2</framework-version>
<bundled>User installed</bundled>
</plugin>Cause
Based on the stacktrace, the third-party app's code flow cannot handle the 'Page Remove' event properly which results with an java.lang.NumberFormatException.
Solution
Upgrade Page Views to the most recent version. If that doesn't work, try disabling the plugin and then attempt to remove the Space again.
