> Project: Apache Knox
> Issue Type: Improvement
> Components: KnoxCLI, Server
> Reporter: Robert Levas

> The file locking mechanism in
> {{org.apache.knox.gateway.services.security.impl.DefaultKeystoreService}}
> today relies on read/write locks to prevent multiple threads from editing a
> single keystore. Java NIO API file locking adds the protection for
> reading/writing from multiple JVMs. Since DefaultKeystoreService is used in
> both gateway and knoxcli, we need to protect against this type of access
> happening at once.
