I've double checked. `Configuration` static methods are using `Configuration.class` as sync object. If we take the classical deadlock example where 2 threads are locking 2 locks in the opposite order: * Thread1 locks `SecurityConfigurationLock` * Thread2 locks `Configuration` (it reads something) * Thread1 tries to lock `Configuration` <= block here * Thread2 does it's job and release `Configuration` lock * Thread1 goes forward, locks and unlocks `Configuration` and finally release the `SecurityConfigurationLock` I think problem would appear when `Configuration` would depend on `SecurityConfigurationLock`, since that is a JVM feature this can't be possible. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
