After upgrading Jira 7.1.9 to 7.5.1 getting URL broken error.

[Shrimann Upadhyay]

After upgrading jira from version 7.1.9 to 7.5.1, I was getting URL broken error and login.jsp file not found error. 

There is no upgrade error found in logs, upgrade was successful and after upgrade jira is running. 

Modified files:
atlassian-jira/WEB-INF/classes/database-defaults/mysql.properties
bin/setenv.sh
conf/server.xml
Removed files:
(none)
Added files:
lib/mysql-connector-java-5.1.39-bin.jar

Above files are modified and added in upgrade process.

Any suggestions would be appreciated.

Hi Shrimann,

There is a bug which might be causing this behaviour:

https://jira.atlassian.com/browse/JRASERVER-62486

also note that there is a driver connection update needed (see the section for "New JDBC driver":

Hope this helps.
