A DESCRIPTION OF THE PROBLEM :
The PowerShell function "Export-PfxCertificate" supports exporting a certificate using either TripleDES_SHA1 or AES256_SHA256. I can open the exported PFX using java.security.keystore when I use TripleDES_SHA1, but not if I use AES256_SHA256.

Steps to reproduce the behavior:
$Cert = dir Cert:\LocalMachine\My | Where-Object -Filter { $_.Thumbprint -eq "0141F6F8D22D8227595D52820D91AEB213725AF7" }                                                                
$PFXPassword = Read-Host "Enter password" -AsSecureString                                                                                                                                
Export-PfxCertificate -Cert $Cert -Password $PFXPassword -FilePath .\TripleDES.pfx -CryptoAlgorithmOption TripleDES_SHA1                                                                 
Export-PfxCertificate -Cert $Cert -Password $PFXPassword -FilePath .\AES256.pfx -CryptoAlgorithmOption AES256_SHA256      

The following code demonstrates the problem:
import java.io.File;
import java.io.FileInputStream;
import java.security.KeyStore;
import java.util.Enumeration;
import java.util.Objects;

public class Main {
	public static void main(String[] args) throws Exception {
		KeyStore keystore;

		File certFile   = new File("AES256.pfx");
		String password = new String("Password");

		try {
			keystore = KeyStore.getInstance("pkcs12");
			keystore.load(new FileInputStream(certFile),
				password.toCharArray());
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

The programs works correctly in openjdk 12+33. Can this support be backported to earlier versions?
