gauth with mongo: CAS crashes when edited cas.properties

[He Vincent]

I have a CAS which is running in production, it gets out of service intermittency.  It annoyed me a lot. I happedned to find out that it was due to I was chaning cas.properties.

I suspected it was due to gauth, I tested it was a prand new configure:

for pom.xml, I added only 2 artifacts:

               <dependency>

                    <groupId>org.apereo.cas</groupId>

                    <artifactId>cas-server-support-gauth</artifactId>

                    <version>${cas.version}</version>

                </dependency>

                <dependency>

                    <groupId>org.apereo.cas</groupId>

                    <artifactId>cas-server-support-gauth-mongo</artifactId>

                    <version>${cas.version}</version>

                </dependency>

For cas.properties, add 2FA and mongoDB itmes:

cas.authn.mfa.gauth.issuer=cs530

cas.authn.mfa.gauth.label=cas530

cas.authn.mfa.gauth.name=cas530

cas.authn.mfa.gauth.trustedDeviceEnabled=true

cas.authn.mfa.gauth.mongo.host=127.0.0.1

cas.authn.mfa.gauth.mongo.port=27017

cas.authn.mfa.gauth.mongo.userId=cas530

cas.authn.mfa.gauth.mongo.password=Welcome1

cas.authn.mfa.gauth.mongo.databaseName=cas530

cas.authn.mfa.gauth.mongo.dropCollection=false

cas.authn.mfa.gauth.mongo.socketKeepAlive=false

cas.authn.mfa.gauth.mongo.retryWrites=false

I started it as:

java -jar target/cas.war

I tested login with casuser:Mellon, works fine:

Then I edited  cas.properties, saved the file, cas got below error:
