"KeyStoreException: Keystore not specified" when only truststore is configured in config client configuration.

[KrishnaST]

I have TLS enabled eureka server. Microservice is trying to fetch configuration from config server throws "KeyStoreException: Keystore not specified" when only truststore is configured. should be able to trust server certificate by truststore configuration. There is no mutual authentication.

Following is micro-service configuration

It seems that there is no way to configure truststore without configuring the keystore even when mutual authentication is not required.

org.springframework.cloud.configuration.SSLContextFactory

Spring Config Client Version : 4.1.3

Is that because builder.loadKeyMaterial throws an exception and we never call builder.loadTrustMaterial? Can you provide a sample to reproduce the error?

[KrishnaST]

Yes, call to loadKeyMaterial will throws a KeystoreException and the execution will never reach the loadTrust.

Here is a minimal sample to reproduce the error and log.
