Don't use the old Java Utils model. `Collections.synchronizedList( new ArrayList<DependencyNode>( 0 ) )` This is still thread-unsafe due to the `ArrayList` is unsafe. Every implementatino of `ArrayList` has two variables (int size, Object[]). Due to this implementation is not safe and due to the writer thread created the object, there is no memorry barrier which would force the thread to write the CPU cache to the main memory and thus there is no guarantee that a reader thread would safely read these variales as initialized. -- This is an automated message from the Apache Git Service.
