Re: [google-cloud-sql-discuss] Exceptions using Cloud SQL MySQL Socket Factory

I've opened https://github.com/GoogleCloudPlatform/cloud-sql-mysql-socket-factory/issues/33, but I can't make any promises about when we can look at it.

The library sets up its own trustStore so I'm surprised that changing JVM settings breaks the library.

We need to figure out how those flags affect the custom trust store and whether we can have it not be affected by those flags.

Removing trustStore allowed it to work.

I also had to adjust my jdbc connection string (specifying user and password params at the end).

This might be problematic though since I needed to configure the trustStore to trust my self-signed certs in order connect to the Datomic transactor. Any ideas?

I would not expect those flags to make a difference since the library manages its own stores... but you never know.

Are you able to to do a test run w/o specifying those ssl flags to see if it makes a difference?

No, separate JVM.

Which JVM are you using?

java version "1.8.0_121"

Java(TM) SE Runtime Environment (build 1.8.0_121-b13)

Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

Would you be able to create a small self-contained repro clojure app?

This might be difficult. The database is Datomic using Cloud SQL as its backing store.

Not sure if it's relevant but I am setting system properties javax.net.ssl.trustStore and Djavax.net.ssl.trustStorePassword to use my own custom trustStore. Would that conflict?

Thanks,

Trevor

Interesting, haven't seen that one before. It seems to indicate a problem setting up certificates within the library.
