(reflect) unexpected cause for TypeNotPresentException

Name: viR10068 Date: 01/22/2004


The API spec for the java.lang.TypeNotPresentException says:
"public TypeNotPresentException(String typeName, Throwable cause)

    Constructs a TypeNotPresentException for the named type with the specified cause.

Parameters:
typeName - the fully qualified name of the unavailable type
cause - the exception that was thrown when the system attempted to load the
named type, or null if unavailable or inapplicable"

But RI always return 'null' instead of actual cause.

The affected test is:
api/java_lang/TypeNotPresentException/index.html#TypeNotPresentException[TypeNotPresentExc
eption0001]

Source code:
---------------------- B.java -------------------------------
import java.io.PrintStream;
class B {
    public static void main(String args[]) {
        Throwable cause = new Throwable("because");
        Throwable par = new Throwable(cause);
        TypeNotPresentException cnp = new TypeNotPresentException("test", par);
    
        try {
            throw cnp;
        } catch (TypeNotPresentException e) {
            System.out.println("Expected cause is " + par.getCause());
            System.out.println("cause is " + e.getCause());
        }
    }
}
