Hi Dasha,
When I echoed the command line I got:
"java.exe" "--add-opens" "java.base/java.lang=ALL-UNNAMED" "-Dswarm.home=C:\hivemq-4.7.2\tools\hivemq-swarm\" -classpath "C:\hivemq-4.7.2\tools\hivemq-swarm\lib\*" com.hivemq.swarm.Main
Running this in the command prompt alone (without running the .bat) resulted in the same weird java output noted above.
This command seemed off to me so I tried removing all the quotations and running this in command prompt:
java.exe --add-opens java.base/java.lang=ALL-UNNAMED -Dswarm.home=C:\hivemq-4.7.2\tools\hivemq-swarm\ -classpath C:\hivemq-4.7.2\tools\hivemq-swarm\lib\* com.hivemq.swarm.Main
And the swarm actually runs properly! Is there something wrong with this operation or is this a safe fix? Were the quotation marks in the .bat file just typos?
Thanks,
Alexi
