Cause
One of the groups from JIRA's "cwd_group" table has empty name.
For JIRA version prior to 4.3, please check the "groupbase" table.
Resolution
In the JIRA database, "cwd_group" table, find what group entry does not have a name and then add a name to it.
For JIRA version prior to 4.3, please check the "groupbase" table.
