virtualAddresses w/mask plus shareAddresses true not idempotent

[wncocz]

Environment

• Application Services Version: 3.49.0 and 3.52.0
• BIG-IP Version: 15.1.10.3

Summary

If a (non-/32) subnet mask is specified on virtualAddresses, and shareAddresses is true, re-posting an already-deployed declaration fails with error. Observed similar behavior whether the virtualAddress is 0.0.0.0/0, 192.168.0.0/16, or 10.13.13.0/24

Steps To Reproduce

Steps to reproduce the behavior:

1. Submit the following declaration:

{
	"class": "ADC",
	"id": "test-0001",
	"schemaVersion": "3.49.0",
	"test": {
		"class": "Tenant",
		"test": {
			"class": "Application",
			"template": "generic",
			"test_fwd24": {
				"class": "Service_Forwarding",
				"forwardingType": "ip",
				"layer4": "udp",
				"allowVlans": [{ "bigip": "/Common/VLAN13" }],
				"profileL4": { "bigip": "/Common/fastL4" },
				"snat": { "use": "test_snat" },
				"virtualAddresses": [
					[ "10.13.13.0/24", "10.12.12.0/23" ]
				],
				"shareAddresses": true,
				"virtualPort": 3999
			},
			"test_snat": {
				"class": "SNAT_Pool",
				"snatAddresses": [
					"10.12.12.12"
				]
			}
		}
	}
}

2. Observe successful deployment
3. Submit it again
4. Observe the following error response:

    results:
    - code: 422
      declarationId: test-0001
      host: localhost
      message: declaration failed
      response: '01020036:3: The requested virtual address (/Common/10.13.13.0/24) was not found.'
      runTime: 12647
      tenant: test

Expected Behavior

Subsequent deployments should succeed without error (or change).

Actual Behavior

Observed error occurs
