The problem is related to Whitelist plugin and there's incomplete regex configured in JIRA. User can generate a support.zip from their JIRA, extract it & check application.xml from support zip/application-properties for <jira.whitelist.rules> entry.
Cause
The problem could be caused by the entry like below:
1
<jira.whitelist.rules>http://www.atlassian.com/* /* http://jira.megatron:8080/* http://jira.megatron:8080/* http://jira.megatron:8060/*</jira.whitelist.rules>
The additional /* character causing this problem.
Solution
Resolution
Backing up data your JIRA and if you have a test instance, it's highly recommended for you to test the suggestion in the test instance before applying it in your production instance.
Stop your JIRA.
Run the following SQL query:
1select * from propertytext where propertyvalue like '%*%';Find the entry /* in propertyvalue column.
Run the following query to remove the data:
1delete from propertytext where id = '<id of the entry with /* value>';Restart JIRA and check whether the same stack trace is still shown.
