How to reload config for Keystore

[WinLordZ]

I have 2 file config to load Keystore softhsm_1 and softhsm_2.
Value for file config changed, but Keystore and all alias not reload. But when I restarting JVM, value loaded with new config. How can i fix it? I've already load and instance keystore like this:

if (pkaSlot.equalsIgnoreCase("0")){
   pkcs11conf = "myPath\\softhsm_1.cfg"; //load config for slot 0
}else pkcs11conf = "myPath\\softhsm_2.cfg"

char[] password = "............".toCharArray();
provider = new sun.security.pkcs11.SunPKCS11(pkcs11conf);               
Security.addProvider(provider);

//Load keystore
keystore = KeyStore.getInstance("PKCS11");
fileInputStream = new FileInputStream(pkcs11conf);
keystore.load(fileInputStream, password);
