Java doesn't read DSA keys from Windows-MY

Question

I have created two different DSA keys using java keytool (defaults to 2048 and SHA256, so the 2nd one is explicitly created with length 1024):

keytool -genkey -keystore c:\test\dsa2048.p12 -storetype pkcs12 -storepass password -keypass password -alias dsa2048

keytool -genkey -keystore c:\test\dsa1024.p12 -storetype pkcs12 -storepass password -keypass password -alias dsa1024 -keysize 1024

I then imported these keys into the windows keystore.

When I read the windows keystore, Keystore.aliases() does not return these ids. It works fine when I use RSA as the keyalg, but DSA doesn't work. I am also able to load these ids if I create the keystore from the file system, but I need to load them from the windows cert store.

Is this expected or is there something else I need to do to see them? Is it possible that keytool is creating invalid ids? When I try to sign with these ids in Acrobat I'm getting an error there as well...

import java.io.FileInputStream;
import java.security.KeyStore;
import java.util.Enumeration;

public class WindowsKeyStoreTest
{
    public static void main(String [] args) throws Exception
    {
        windowsKeystore();
    }
    
    public static void windowsKeystore() throws Exception
    {
        KeyStore keyStore = KeyStore.getInstance("Windows-MY");
        keyStore.load(null, null);
        Enumeration<String> aliases = keyStore.aliases();
        while(aliases.hasMoreElements())
        {
            String alias = aliases.nextElement();
            if(keyStore.isKeyEntry(alias))
            {
                System.out.println(alias);
            }
        }
    }
}
