Motivation
When using Pulsar with IPv6, it's necessary to set
-Djava.net.preferIPv4Stack=falsesince Pulsar startup scripts set-Djava.net.preferIPv4Stack=true. Currently it's not possible to override the Pulsar default by passing-Djava.net.preferIPv4Stack=falseinOPTSenvironment variable. This PR intends to make it possible.This PR is related to the issue #23843.
Modifications
Prepend the default value
-Djava.net.preferIPv4Stack=truetoOPTSinstead of appending to it so that the setting inOPTStakes preference. The last setting in the argument line wins when setting system properties for Java processes.Documentation
