Error: "Element type "f0gL" must be followed by either attribute specifications, ">" or "/> (4314533)

When starting Foglight/vFoglight via service or via command line, the server fails to start up during the Database Lifecycle startup step. Within the Foglight Management Server Log, the following can be seen:

YYYY-MM-DD HH:MM:SS.SSS ERROR [main] STDERR - [Fatal Error] :1:394: Element type "f0gL" must be followed by either attribute specifications, ">" or "/>".

YYYY-MM-DD HH:MM:SS.SSS VERBOSE [main] org.jboss.system.ServiceConfigurator - Problem configuring service jboss.jca:service=ManagedConnectionFactory,name=jdbc/nitrogen
org.jboss.util.NestedRuntimeException: Element type "f0gL" must be followed by either attribute specifications, ">" or "/>".; - nested throwable: (org.xml.sax.SAXParseException: Element type "f0gL" must be followed by either attribute specifications, ">" or "/>".)
 

What is causing this?

This denotes that special characters "<" and ">" are being used in the Foglight SQL Server (backend) database password. SQL Server accepts this, but when Foglight connects to this database with the same credentials, Foglight does not start up successfully because the characters "<" and ">" corrupt the XML config on which Foglight is dependent. Please use a password that does not contain the special characters of "<" and ">".

FDOC-1925 has been raised to adjust the Foglight documentation to state that these special characters should not be used.
