oracle jdk DOWNGRADE

Affected: 1.6.0 update101 · 1.7.0 update85 · 1.8.0 update60

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.6.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.6.0 (Debian / Ubuntu)

apt-cache madison jdk sudo apt install jdk=<VERSION_BEFORE_1.6.0> sudo apt-mark hold jdk

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

dnf --showduplicates list jdk sudo dnf downgrade jdk-<VERSION_BEFORE_1.6.0> sudo dnf versionlock add jdk

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.

apt-cache madison jre sudo apt install jre=<VERSION_BEFORE_1.6.0> sudo apt-mark hold jre

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

dnf --showduplicates list jre sudo dnf downgrade jre-<VERSION_BEFORE_1.6.0> sudo dnf versionlock add jre

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.
