Red Hat Single Sign-On (RH SSO) fails to start in OpenShift Container Platform (OCP) when using FIPS

Issue

• We have FIPS enabled on the cluster:

  $ oc get cm <ConfigMap> -n <Project> -o yaml | grep -i "fips"
  fips: true
  

  The following message is displayed on the RH SSO's pod's startup:

  •[0;33mWARN No password defined for JGroups cluster. AUTH protocol will be disabled. Please define JGROUPS_CLUSTER_PASSWORD.•[0m
  INFO Configuring JGroups discovery protocol to dns.DNS_PING
  INFO Creating HTTPS keystore via OpenShift's service serving x509 certificate secrets..
  

  And then it exits abruptly, switching the status to CrashLoopBackOff.

• With a fips: true OpenShift cluster the RH SSO images fail to start giving the error:

  Importing keystore /opt/eap/keystores/jgroups-keystore.pk12 to /opt/eap/keystores/jgroups-keystore.jks...
  keytool error: java.io.IOException: parseAlgParameters failed: PBE AlgorithmParameters not available
