4 java/net tests failed on Mac_OS_X_14.1.2

The following tests failed in the JDK22 CI:

java/net/MulticastSocket/SetOutgoingIf.java
java/net/MulticastSocket/SetLoopbackModeIPv4.java
java/net/DatagramSocket/DatagramSocketMulticasting.java
java/net/DatagramSocket/DatagramSocketExample.java

Four java/net test failures in one job set is rare so I'm wondering
if there's some kind of interference here:

java/net/MulticastSocket/SetOutgoingIf.java
  end=Sat Dec 02 10\:17\:25 GMT 2023
  start=Sat Dec 02 10\:17\:19 GMT 2023

java/net/MulticastSocket/SetLoopbackModeIPv4.java
  end=Sat Dec 02 10\:17\:21 GMT 2023
  start=Sat Dec 02 10\:17\:18 GMT 2023

java/net/DatagramSocket/DatagramSocketMulticasting.java
  end=Sat Dec 02 10\:15\:28 GMT 2023
  start=Sat Dec 02 10\:04\:37 GMT 2023

java/net/DatagramSocket/DatagramSocketExample.java
  end=Sat Dec 02 10\:15\:27 GMT 2023
  start=Sat Dec 02 10\:04\:36 GMT 2023

It looks like these two overlapped with each other, but not with
the last two:
java/net/MulticastSocket/SetOutgoingIf.java
java/net/MulticastSocket/SetLoopbackModeIPv4.java

It looks like these two overlapped with each other, but not with
the first two:
java/net/DatagramSocket/DatagramSocketMulticasting.java
java/net/DatagramSocket/DatagramSocketExample.java
