原因

The database is corrupted. There is a custom field value associated to a 'NULL' issue.

ソリューション

1. Jira を停止します。

2. Perform the following SQL query to check whether there are any custom fields assigned to 'NULL' issue. You should get

   select * from customfieldvalue where ISSUE is null; 
   +-------+-------+-------------+-----------+------------------+-------------+-----------+-----------+-----------+
   | ID    | ISSUE | CUSTOMFIELD | PARENTKEY | STRINGVALUE      | NUMBERVALUE | TEXTVALUE | DATEVALUE | VALUETYPE |
   +-------+-------+-------------+-----------+------------------+-------------+-----------+-----------+-----------+
   | 36625 |  NULL |       10000 | NULL      | Field value      |        NULL | NULL      | NULL      | NULL      | 
   +-------+-------+-------------+-----------+------------------+-------------+-----------+-----------+-----------+
   1 row in set (0.00 sec)
   

3. Remove the custom field value:

   delete from customfieldvalue where issue is null;
   

4. Jira を再起動します。
