When IXP server is started up using Java 9, the following message pops up upon user's login to IXP and job data are not loaded: "Error refreshing job data".
Java 9 is not supported according to the Support Matrix for CA Workload Automation IXP 11.3.5.
the IXP Compatibility Matrix can be found at the following URL: https://docops.ca.com/ca-workload-automation-ixp/11-3-5/en/release-notes/compatibility-matrix
Java 9 has been labeled a "short term release".
We have no plans to implement support for it.
