oracle jrockit DOWNGRADE

Affected: r27.8.1 · r28.3.1

Fixed in: no fixed release known

Safe to downgrade to: a release before r27.8.1

1. Check installed version

apt-cache policy jrockit || rpm -q jrockit || jrockit --version

2. No fixed release: DOWNGRADE to a release before r27.8.1 (Debian / Ubuntu)

apt-cache madison jrockit sudo apt install jrockit=<VERSION_BEFORE_r27.8.1> sudo apt-mark hold jrockit

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list jrockit sudo dnf downgrade jrockit-<VERSION_BEFORE_r27.8.1> sudo dnf versionlock add jrockit

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
