Install/install ➜ Installation of JDK RPM Corrupts Alternatives Alternatively, the '-XX:-UsePerfData' JVM option can be used to prevent JVMs running within different containers from writing performance data to the shared /tmp folder and thus avoid this issue. In earlier releases, this crash can be avoided by mounting /tmp to different locations for different containers. JDK-8286030: This release addresses an issue where Java applications may encounter a fatal error when the same /tmp directory is shared across multiple containers. In the previous release, this situation can be avoided by using either -XX:-UseContainerSupport, or -XX:MaxRAM=, or by setting a memory limit for your container that is lower than the physical memory. JDK 8u381 addresses this stability issue. JDK-8292083: Java applications may experience out-of-memory errors and run the risk of being killed by the OOM killer when running in a containerized environment where the container is configured with a higher memory limit than the available physical memory on the host system. Some of the notable stability enhancements are: The improvements include accurately detecting the resource limits of containers, correctly reporting the collected container metrics, printing additional container information, and improving application stability in containerized environments. JDK 8u381 includes several enhancements and fixes to improve the cgroup v1 and v2 support for containers.

After either condition is met (new release becoming available or expiration date reached), the JRE will provide additional warnings and reminders to users to update to the newer version. Java SE Subscription customers managing JRE updates/installs for large number of desktops should consider using Java Advanced Management Console (AMC).įor systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u381) on. It is not recommended that this JDK (version 8u381) be used after the next critical patch update scheduled for October 17, 2023. In order to determine if a release is the latest, the Security Baseline page can be used to determine which is the latest version for each release family.Ĭritical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Bulletins.
