Breaking changes in 6.2edit

This section discusses the changes that you need to be aware of when migrating your application to Elasticsearch 6.2

All permission bootstrap checkedit

Elasticsearch installs a security manager during bootstrap to mitigate the scope of exploits in the JDK, in third-party dependencies, and in Elasticsearch itself as well as to sandbox untrusted plugins. A custom security policy can be applied and one permission that can be added to this policy is java.security.AllPermission. However, this effectively disables the security manager. As such, granting this permission in production mode is now forbidden via the all permission bootstrap check.
