Able to control knx rf unsecure , but getting senders as null issue in knx rf secure

[bhanujarya]

I have successfully controlled the Unsecure calimero relay using Java 17 and latest calimero.io dependency , but when reading status of secured device i am getting senders as null , attaching my security method below

private void enableSecurity(Security security) {
		try {
			String groupAddress = "2309";
			GroupAddress addr = getGroupAddressObj(groupAddress);
			byte[] key = null;
			key = getByteArray("9PgLPd0h6kKXQvCwMfq1Uw==");
			
			Security.newSecurity().groupKeys().put(addr, key);
			IndividualAddress address = new IndividualAddress("2309");
			Set<IndividualAddress> individualSet = new HashSet<>();
			individualSet.add(address);
			security.groupSenders().put(addr, individualSet);
			security.groupKeys().put(addr, key);
			
			
			  useKeyring(Keyring.load(keyringUri), keyringPwd);
			  security.useKeyring(Keyring.load(keyringUri), keyringPwd);
			 

			

		} catch (Exception e) {
			e.printStackTrace();
			System.err.println("Exception : in securing rf " + e);
		}
	}

Please help me know how to resolve this
