I try to start this tool after unpack the release tarball（silk-workbench-v3.6.0.tgz）:

My command is:

 sgdd@sgdd-PowerEdge-R730xd:/opt/silk-workbench-v3.6.0/bin$]

export JAVA_HOME=/opt/jdk-11.0.16  && ./silk-workbench  -Dplay.http.secret.key='QCY?tAnfk?aZ?iwrNwnxIlR6CTf:G3gf:90Latabg@5241AB`R5W:1uDFN];Ik@n'    -Dworkbench.host="26.28.189.4:9765"   -Dplay.server.http.port=9765     -Dpidfile.path=/dev/null    -jvm-debug 19765
