Can you just confirm with me what database and version you're using? The error could be caused by a lot of things.

There was another user in the past that had the issue, and he explains below how it was resolved:

* [Unable to reinstall Confluence, different Java errors at different stages.](https://community.atlassian.com/t5/Confluence-questions/Unable-to-reinstall-Confluence-different-Java-errors-at/qaq-p/790011#M107077)
