Overwritten Map, Set, or array element
Reports code that overwrites a Map key, a Set element, or an array element in a sequence of add/put calls or using a Java 9 factory method like Set.of (which will result in runtime exception).
This usually occurs due to a copy-paste error.
Example:
map.put("A", 1);
map.put("B", 2);
map.put("C", 3);
map.put("D", 4);
map.put("A", 5); // duplicating key "A", overwrites the previously written entry
