Upgrading to 3.5.20 results in a java.lang.AbstractMethodError
Upgrading the Support Tools Plugin throws a java.lang.AbstractMethodError, which prevents pages from being rendered. This effectively renders Confluence useless.
The following error is thrown in the logs:
And this error shows up in the UI:
Steps to Reproduce
Launch Confluence v.5.2.3
Upload the plugin file for STP v.3.5.20
Navigate to the dashboard
Confluence versions 5.2.3, 5.2.5
In case this is of interest to anybody, I also created a blog about my own experience with this (now resolved) issue including the provided fixes/workarounds in case you run into this: http://www.luke1410.de/blog/?p=57
So this actually worked (uninstalling STP 3.5.28 and then reinstalling STP 3.5.10). Afterwards the upgrade to Confluence 5.2.5 worked without any issues. Thanks for the help once again.
Hi , thanks for the info. That helps alot I guess. Will give it a try later if downgrading STP works here.
Hey , Support tools plugin 3.5.20 and above is not compatible with Confluence 5.2.5 series. We fixed this typo in version 3.5.20 as you can see in marketplace:
However in the new releases we can see the compatibility shows for confluence 4.3 which is incorrect . While we address that please, downgrade the add on prior 3.5.20 or upgrade Confluence to 5.3.
Do the upgrade on a staging environment.
Thanks and Regards,

In which version was this fixed? I'm running into the same error message described here when upgrading Confluence 5.1.5 -> 5.2.5, though we are running STP 3.5.28.
