      When clicking on the Dead link in the executors widget:

      java.lang.IndexOutOfBoundsException: Index: 1, Size: 1
	at java.util.ArrayList.rangeCheck(Unknown Source)
	at java.util.ArrayList.get(Unknown Source)
	at hudson.model.queue.MappingWorksheet$ReadOnlyList.get(MappingWorksheet.java:102)

	at hudson.model.Executor.run(Executor.java:206)

      Looking at the code

      assert capacity() >= wc.size();
int e = 0;
for (SubTask s : wc) {
    while (!get(e).isAvailable()) // IOOBE
        e++;
    get(e++).set(wuc.createWorkUnit(s));
}

      it seems wrong: when isAvailable is false, you are almost sure to run out of slots, since there is no range check on e.
