[jira] Created: (HARMONY-1161) [classlib][luni]
java.util.TreeMap.subMap(Object, Object).size() throws unspecified NPE.
[classlib][luni] java.util.TreeMap.subMap(Object, Object).size() throws unspecified NPE.
----------------------------------------------------------------------------------------
Key: HARMONY-1161
URL: http://issues.apache.org/jira/browse/HARMONY-1161
Project: Harmony
Issue Type: Bug
Components: Classlib
Reporter: spark shen
java.util.TreeMap.subMap(Object, Object).size() throws unspecified NPE under
certain case. Demonstrated below:
Code snippet:
class MockComparatorNullTolerable implements Comparator<String> {
public int compare(String o1, String o2) {
if( o1 == o2 ) {
return 0;
}
if( null == o1 ) {
return -1;
}
return o1.compareTo(o2);
}
}
public CollationKey getCollationKey(String arg0) {
return null;
}
public int hashCode() {
return 0;
}
}
public void test_subMapLjava_lang_ObjectLjava_lang_Object() {
TreeMap<String, String> map1 = new TreeMap<String, String>(new
MockComparatorNullTolerable ());
map1.put("key1" , "value1");
map1.put(null, "value1");
SortedMap<String, String> subMap = map1.subMap( null, "key1");
assertEquals("Size of subMap should be 1:", 1, subMapWithNull.size());
}
When subMap.size() is called on Harmony, a NullPointerException will be thrown
out. But On RI, no such exception will be thrown out.
