FYI, I just figured out that Java was not successfully starting up with NSO 4.4.2 and the latest Juniper and IOSXR NEDs on my Mac because the 512M Java heap size is not longer big enough. ISO and NX and 4.4.2 are still ok, but if you want to run with Juniper and/or ISOXR, you will need to bump your startup heap to 1024M by setting NCS_JAVA_VM_OPTIONS="-X1024M".
