WebSphere Liberty Profile on macOS - SuperSnooping

So I've run this on Liberty multiple times, including most recently on my Mac, natively.

This is what I have: -

Check Liberty Version

~/Downloads/wlp/bin/server version

objc[43120]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_112.jdk/Contents/Home/bin/java (0x10761e4c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_112.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x1077184e0). One of the two will be used. Which one is undefined.
WebSphere Application Server 16.0.0.2 (1.0.13.cl160220160526-2258) on Java HotSpot(TM) 64-Bit Server VM, version 1.8.0_112-b16 (en_GB)


Check server.xml

cat ~/Downloads/wlp/usr/servers/defaultServer/server.xml

<server description="new server">

    <!-- Enable features -->
    <featureManager>
        <feature>webProfile-7.0</feature>
        <feature>adminCenter-1.0</feature>
        <feature>localConnector-1.0</feature>
    </featureManager>

    <classloading useJarUrls="true"/>

    <quickStartSecurity userName="admin" userPassword="{xor}Lz4sLCgwLTs="/>

    <keyStore id="defaultKeyStore" password="{xor}EzY9Oi0rJg=="/>

    <!-- To access this server from a remote client add a host attribute to the following element, e.g. host="*" -->
    <httpEndpoint httpPort="9080" httpsPort="9443" id="defaultHttpEndpoint"/>
                  
    <!-- Automatically expand WAR files and EAR files -->
    <applicationManager autoExpand="true"/>

    <remoteFileAccess>
        <writeDir>${server.config.dir}</writeDir>
    </remoteFileAccess>


    <applicationMonitor updateTrigger="mbean"/>

Check Dropins

ls -al ~/Downloads/wlp/usr/servers/defaultServer/dropins/

I also downloaded the latest WLP: -

-rw-r--r--@  1 davidhay  staff  69984067 27 Jan 18:21 wlp-webProfile7-16.0.0.4.zip

...
WebSphere Application Server 16.0.0.4 (1.0.15.cl160420161113-0206) on Java HotSpot(TM) 64-Bit Server VM, version 1.8.0_112-b16 (en_GB)
...

from here: -

Get started with Liberty

and again SuperSnoopServlet worked without problems, with a default server.xml : -

<?xml version="1.0" encoding="UTF-8"?>
<server description="new server">

    <!-- Enable features -->
    <featureManager>
        <feature>webProfile-7.0</feature>
    </featureManager>

    <!-- To access this server from a remote client add a host attribute to the following element, e.g. host="*" -->
    <httpEndpoint id="defaultHttpEndpoint"
                  httpPort="9080"
                  httpsPort="9443" />
                  
    <!-- Automatically expand WAR files and EAR files -->
    <applicationManager autoExpand="true"/>

Fun, fun, fun
