FULL PRODUCT VERSION :
Java 2 Runtime Environment, Standard Edition (build 1.5.0-b64)
Java Hotspot (TM) Client VM (build 1.5.0-b64, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
The following code fails to compile:

// MyCallable.java
import java.util.*;
import java.util.concurrent.*;

public class MyCallable<V extends Boolean> implements Callable<Boolean> {
public Boolean call() {
return new Boolean(true);
}

public static void main(String[] main) throws Exception {
Collection<Callable> callables = new TreeSet<Callable>();
callables.add(new MyCallable());
ExecutorService executor = Executors.newCachedThreadPool();
executor.invokeAll(callables);
}
}
// end of MyCallable.java

javac produces the following error message:
MyCallable.java:13: cannot find symbol
symbol : method invokeAll(java.util.Collection<java.util.concurrent.Callable>
location: interface java.util.concurrent.ExecutorService

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
javac -source 1.5 MyCallable.java

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I was exepecting the code to compile without problems. The code compiles fine with the Eclipse compile on Eclipse on 3.1.0 build 200412162000
ACTUAL -
MyCallable.java:13: cannot find symbol
symbol : method invokeAll(java.util.Collection<java.util.concurrent.Callable>
location: interface java.util.concurrent.ExecutorService

ERROR MESSAGES/STACK TRACES THAT OCCUR :
MyCallable.java:13: cannot find symbol
symbol : method invokeAll(java.util.Collection<java.util.concurrent.Callable>
location: interface java.util.concurrent.ExecutorService

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
// MyCallable.java
import java.util.*;
import java.util.concurrent.*;

public class MyCallable<V extends Boolean> implements Callable<Boolean> {
public Boolean call() {
return new Boolean(true);
}

public static void main(String[] main) throws Exception {
Collection<Callable> callables = new TreeSet<Callable>();
callables.add(new MyCallable());
ExecutorService executor = Executors.newCachedThreadPool();
executor.invokeAll(callables);
}
}
// end of MyCallable.java
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
The code compile if you remove generics from the Collection callables.
