disruptor/src/main/java/com/lmax/disruptor/SingleProducerSequencer.java

Line 102 in 109e288

if (wrapPoint > cachedGatingSequence || cachedGatingSequence > nextValue)

What case will run this code “cachedGatingSequence > current” ? Could Consumer's sequence be more than Producer's sequence ? But this case can be possible ?
