oracle java virtual machine UPGRADE

Affected: >= 19.3 and <= 19.30 · >= 21.3 and <= 21.21

Fixed in: newer than 21.21

Safe to downgrade to: a release before 19.3

1. Check installed version

apt-cache policy java-virtual-machine || rpm -q java-virtual-machine || java-virtual-machine --version

2. UPGRADE to newer than 21.21 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade java-virtual-machine

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade java-virtual-machine

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 19.3 (Debian / Ubuntu)

apt-cache madison java-virtual-machine sudo apt install java-virtual-machine=<VERSION_BEFORE_19.3> sudo apt-mark hold java-virtual-machine

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list java-virtual-machine sudo dnf downgrade java-virtual-machine-<VERSION_BEFORE_19.3> sudo dnf versionlock add java-virtual-machine

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.
