Attributes

Remarks

Possibly atomically sets the value to newValue if the current value == expectedValue, with memory effects as specified by VarHandle#weakCompareAndSetPlain.

This member is deprecated. This method has plain memory effects but the method name implies volatile memory effects (see methods such as #compareAndExchange and #compareAndSet). To avoid confusion over plain or volatile memory effects it is recommended that the method #weakCompareAndSetPlain be used instead.
