Package: gij-4.1
Version: 4.1.2-6
Severity: normal
The gij implementation of EnumMap class contains a flaw: it returns
strange java.lang.Object classes for missing elements. The error can be
demonstrated with this program:
=== Cut ===
import java.util.*;
public class Test {
enum TestEnum {
FIRST, SECOND
}
public static void main(String[] args) {
Map<TestEnum, String> map = new EnumMap<TestEnum,
String>(TestEnum.class);
map.put(TestEnum.FIRST, "first");
System.out.println(map);
System.out.println(map.containsKey(TestEnum.SECOND));
System.out.println(map.get(TestEnum.SECOND));
}
}
=== Cut ===
tmp $ gcj-4.1 -C Test.java
tmp $ gij-4.1 Test
{FIRST=first}
false
Exception in thread "main" java.lang.ClassCastException:
java.lang.Object cannot be cast to java.lang.String
at Test.main(Test.java:13)
tmp $ java Test
{FIRST=first}
false
null
=== Cut ===
As you can see, Sun Java (the last call) returns correct null, while
GNU libgcj returns bogus java.lang.Object. gij-4.2 from experimental
gives the same error.
