To programmatically handle this, The following code in Scala will help you do it. The code given above will not work for java version 8. You will get an error. Error : Can not set static final boolean field javax.crypto.JceSecurity.isRestricted to java.lang.Boolean

if (Cipher.getMaxAllowedKeyLength("AES") < 256) {
 try {
 var field=Class.forName("javax.crypto.JceSecurity").getDeclaredField("isRestricted")
    field.setAccessible(true)
   var modifiersField = classOf[Field].getDeclaredField( "modifiers" )
   modifiersField.setAccessible(true);
   modifiersField.setInt(field, field.getModifiers() & ~Modifier.FINAL);
    field.set(null, java.lang.Boolean.FALSE)
  }

  catch{
    case ex:Exception=>throw ex
  }
}
