After making changes to server.xml your Atlassian application fails to start and the following message appears in catalina.out:

06-Jul-2016 09:44:47.930 WARNING [main] org.apache.catalina.startup.Catalina.load Catalina.start using /var/atlassian/application-data/bitbucket/shared/server.xml: Element type "Connector" must be followed by either attribute specifications, ">" or "/>".


The syntax for the Connector element in server.xml is invalid. This can be caused by incorrect use of spaces, using tabs, or other syntax errors.


Verify that no tabs are used in the Connector block an all attributes are syntactically correct. After finding the offending character, correct it and restart the application.
