17.10 openjdk and oracle jdk 8 and 9 the trustAnchors parameter must be non-empty

I reinstalled everything using apt-get and that didn't solve the problem.

The solution that I found to work: Go to Oracle and download the tar.gz version of jdk-8. Then copy the cacerts file from that into /etc/ssl/certs/java/cacerts

I ran into this issue as well when trying to set up scala build tool (sbt) on my fresh 17.10 installation.

My solution was to purge:

sudo apt purge openjdk-9-jdk openjdk-8-jdk java-common

(Just purging and reinstalling the jdk was not enough, I still had a java command after that. Only by purging java-common that also went away and then reinstallation worked. I assume it relates to the ca-certificates-java* package, that gets purged by java-common.)

Afterwards, I reinstalled java again (I opted only for openjdk-9):

sudo apt install openjdk-9-jdk

This triggered: Running hooks in /etc/ca-certificates/update.d... and added a lot of cert files. Now my sbt built was succesful:

$ sbt
Getting org.scala-sbt sbt 1.1.0  (this may take some time)...

downloading https://repo1.maven.org/maven2/org/scala-sbt/main_2.12/1.1.0/main_2.12-1.1.0.jar
...  

I have reinstalled everything from scratch again and this problem has disappeared. All I did differently was install openjdk-8-jdk prior to installing openjdk-9-jdk.

It works. Are there any weird dependency issues?
