[jira] Created: (ADDR-13) some methods in java.util.Collections
don't throw NPE when the parameter is null
some methods in java.util.Collections don't throw NPE when the parameter is null
---------------------------------------------------------------------------------
Key: ADDR-13
URL: http://issues.apache.org/jira/browse/ADDR-13
Project: Addressing
Type: Bug
Reporter: Svetlana Samoilenko
According to j2se 1.4.2 and 1.5 specification for the Collections class "The methods of this class all throw a NullPointerException if the collections provided to them are null".
Harmony does not throw NPE for some methods.
Code to reproduce:
import java.util.*;
public class test2 {
public static void main(String [] args) {
SortedMap m = null;
Map map=null;
Set set=null;
SortedSet sortedset=null;
SortedMap sortedmap =null;
Collection col=null;
try {
Collections.synchronizedCollection(col);
System.out.println("synchronizedCollection(null) must throw NPE");
} catch (NullPointerException e) {
System.out.println("PASSED");
}
try {
Collections.synchronizedSortedMap(sortedmap);
System.out.println("synchronizedSortedMap(null) must throw NPE");
} catch (NullPointerException e) {
System.out.println("PASSED");
}
try {
Collections.synchronizedMap(map);
System.out.println("synchronizedMap(map) must throw NPE");
} catch (NullPointerException e) {
System.out.println("PASSED");
}
try {
Collections.synchronizedSet(set);
System.out.println("synchronizedSet(set) must throw NPE");
} catch (NullPointerException e) {
System.out.println("PASSED");
}
try {
Collections.synchronizedSortedSet(sortedset);
System.out.println("synchronizedSortedSet(null) must throw NPE");
} catch (NullPointerException e) {
System.out.println("PASSED");
}
try {
Collections.unmodifiableCollection(col);
System.out.println("unmodifiableCollection(null) must throw NPE");
} catch (NullPointerException e) {
System.out.println("PASSED");
}
try {
Collections.unmodifiableMap(map);
System.out.println("unmodifiableMap(null) must throw NPE");
} catch (NullPointerException e) {
System.out.println("PASSED");
}
try {
Collections.unmodifiableSet(set);
System.out.println("unmodifiableSet(null) must throw NPE");
} catch (NullPointerException e) {
System.out.println("PASSED");
}
try {
Collections.unmodifiableSortedMap(sortedmap);
System.out.println("unmodifiableSortedMap(null) must throw NPE");
} catch (NullPointerException e) {
System.out.println("PASSED");
}
try {
Collections.unmodifiableSortedSet(sortedset);
System.out.println("unmodifiableSortedSet(null) must throw NPE");
} catch (NullPointerException e) {
System.out.println("PASSED");
}
}
}
Steps to Reproduce:
1. Build Harmony (check-out on 2006-01-30) j2se subset as described in README.txt.
2. Compile test2.java using BEA 1.4 javac
> javac -d . test2.java
3. Run java using compatible VM (J9)
> java -showversion test2
Output:
C:\tmp>C:\jrockit-j2sdk1.4.2_04\bin\java.exe -showversion test2
java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
BEA WebLogic JRockit(TM) 1.4.2_04 JVM (build ari-31788-20040616-1132-win-ia32, Native Threads, GC strategy: parallel)

unmodifiableMap(null) must throw NPE
unmodifiableSet(null) must throw NPE
unmodifiableSortedMap(null) must throw NPE
unmodifiableSortedSet(null) must throw NPE
Suggected fix and test in attachment.
