Applications Manager's Java Client is officially supported and compatible with Windows only. However, a workaround was found by the Broadcom community. See original post here.
NOTE that this is not an official workaround and may not work with Applications Manager version 9.4.2 or above. Use at your own discretion and if needed, please refer/update the original community post.
Release : 9.3.x, 9.4.x
Create a shell script (e.g. UC4Client.sh) that will set Client/Java environment and call the RunClient.jar
Example UC4Client.sh contents:
$JAVA_HOME/bin/java -cp ".:./jars/*" -Dappworx.debug=true -DAW_HOME="$RUNDIR/RunClient.jar" -Xmx256m com.appworx.client.screen.main.AxMain
