URL: https://github.com/apache/accumulo/issues/3867
**Test name(s)**
-
org.apache.accumulo.test.functional.GarbageCollectorIT.testRootUniqueMutationDelete
**Describe the failure observed**
An assertion that there were no delete candidates prior to the test code
running failed. The relevant test code and assertion:
```java
// Ensure that no other candidates exist before starting test.
Iterator<GcCandidate> cIter = ample.getGcCandidates(datalevel);
ArrayList<GcCandidate> tempCandidates = new ArrayList<>();
while (cIter.hasNext()) {
GcCandidate cTemp = cIter.next();
log.debug("PreExisting Candidate Found: {}", cTemp);
tempCandidates.add(cTemp);
}
assertTrue(tempCandidates.size() == 0);
```
The failure was:
```

**What have you tried already?**
The IT got re-run, and passed on a subsequent attempt.
**Additional context**
This code is similar in 2.1, so any failure here is probably applicable to
2.1 as well.
The `assertTrue(size == 0)` should also be changed to `assertEquals(0, size)`
