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.
