The LineEvent class in package javax.sound.sampled is Serializable by inheritage, but it would be impossible to make it Serializable (i.e. the Line interface would have to be made Serializable, too). Consequently, LineEvent should be explicitely marked "Not Serializable".
This would also satisfy the JCK problem, I assume: LineEvent's inner class, LineEvent.Type, is not Serializable. This is therefore a re-open of RFE 4335276.
