Problem
The Memory Information under Administration > System > System Info displays 0% Free MetaSpace:
Environment
JIRA applications running with Java 1.8 or later.
The -XX:MaxMetaspaceSizeJVM argument is not configured.
Cause
This is the expected behavior.
Java 8 replaces the PermGen memory area with MetaSpace, which is dynamically allocated on native memory. The amount of native memory that can be used for class metadata is by default unlimited and managed by the JVM automatically.

Resolution
No action is required - This is the expected behavior.
