When using UCP 184.108.40.206.0 or 220.127.116.11.0 with RAC 18.104.22.168.0 server, FCF does not work. To observe the problem, either turn on UCP logging or obtain
FCF statistics after an injected outage. The log would show the received FAN event as invalid; and the statistics string would show no FCF processing has taken place.
UCP throws java.sql.SQLRecoverableException as follows:
The issue reproduces with both UCP 22.214.171.124 and 126.96.36.199.
The JDBC version is not relevant to to the reproducibility.
