restoredIntervalEnd logic is wrong
```
public static GtidSet fixRestoredGtidSetOld(GtidSet serverGtidSet,
GtidSet restoredGtidSet) {
Map<String, GtidSet.UUIDSet> newSet = new HashMap<>();
serverGtidSet.getUUIDSets().forEach(uuidSet ->
newSet.put(uuidSet.getUUID(), uuidSet));
for (GtidSet.UUIDSet uuidSet : restoredGtidSet.getUUIDSets()) {
GtidSet.UUIDSet serverUuidSet = newSet.get(uuidSet.getUUID());
if (serverUuidSet != null) {
long restoredIntervalEnd = getIntervalEnd(uuidSet);
List<com.github.shyiko.mysql.binlog.GtidSet.Interval>
newIntervals =
new ArrayList<>();
for (GtidSet.Interval serverInterval :
serverUuidSet.getIntervals()) {
if (serverInterval.getEnd() <= restoredIntervalEnd) {
newIntervals.add(
new
com.github.shyiko.mysql.binlog.GtidSet.Interval(
serverInterval.getStart(),
serverInterval.getEnd()));
} else if (serverInterval.getStart() <=
restoredIntervalEnd
&& serverInterval.getEnd() >
restoredIntervalEnd) {
newIntervals.add(
new
com.github.shyiko.mysql.binlog.GtidSet.Interval(
serverInterval.getStart(),
restoredIntervalEnd));
}
}
newSet.put(
uuidSet.getUUID(),
new GtidSet.UUIDSet(
new
com.github.shyiko.mysql.binlog.GtidSet.UUIDSet(
uuidSet.getUUID(), newIntervals)));
} else {
newSet.put(uuidSet.getUUID(), uuidSet);
}
}
return new GtidSet(newSet);
}
