Uses of SimpleDateFormat without synchronization #6

Open DamianFekete opened 8 years ago

DamianFekete commented 8 years ago

The dateFormat field from AbstractController.java is used in controllers without thread synchronization.

Synchronization Date formats are not synchronized. It is recommended to create separate format instances for each thread. If multiple threads access a format concurrently, it must be synchronized externally.
