Cache security

Access to the shared class cache is limited by operating system permissions and Java™ security permissions.

By default, class caches are created with user-level security, so only the user that created the cache can access it. On z/OS® UNIX, there is an option, groupAccess, which gives access to all users in the primary group of the user that created the cache. However, regardless of the access level used, a cache can only be destroyed by the user that created it or by a root user (UID 0).

Refer to Java SDK and Runtime Environment User Guide to learn more about extra security options using a Java SecurityManager.
