Problem
The export of Bamboo fails and the following error is found in the atlassian-bamboo.log:
2019-06-03 14:48:32,886 ERROR [http-nio-8085-exec-25] [Export] org.springframework.orm.hibernate5.HibernateSystemException: Cannot instantiate abstract class or interface: : com.atlassian.bamboo.deployments.projects.persistence.items.AbstractMutableDeploymentProjectItem; nested exception is org.hibernate.InstantiationException: Cannot instantiate abstract class or interface: : com.atlassian.bamboo.deployments.projects.persistence.items.AbstractMutableDeploymentProjectItem

Cause
This issue is caused by database corruption introduced by a bug in Bamboo, BAM-19948 - Getting issue details... STATUS .
Note: Even if you may be running Bamboo 6.6.2 or newer (which do not contain the bug anymore), the corruption may still be in the database.
Resolution
To resolve this problem, first upgrade Bamboo to version 6.6.2 or newer to prevent the corruption from reoccurring. Once the upgrade was successful, follow these steps to have Bamboo repair the database corruption:
- Create a new plan with an artifact definition. This plan needs no content other than an artifact definition and its sole purpose is to be removed and in the next step.
- Remove this new plan created in step 1. This will trigger Bamboo to execute a DB cleanup and removes orphaned Artifact definition records which triggers the bug in affected plans.
