Symptoms

When trying to start JIRA, the homepage in the browser reports that JIRA has been locked.

The following appears in the atlassian-jira.log:

No enum constant com.atlassian.crowd.model.membership.MembershipType.GROUP USER

Diagnosis

To diagnose if this is the issue affecting your JIRA, run the following query against your database:

SELECT DISTINCT membership_type FROM cwd_membership WHERE membership_type LIKE '% %';

This command must return an empty set. Substitute an underscore for a space in every membership_type returned.

Cause

This is caused by the use of an enumerator to store the membership values; the space is an invalid character in that position.

Resolution

• Substitute an underscore for a space in every membership_type returned in the previous query.
