COSBench 0.4.2 does not start up in Ubuntu 20.04

[thatsdone]

DESCRIPTION

COSBench 0.4.2.0 does not start up under the following conditions (at least).
start-driver.sh fails to wait for successful initialization of various cosbench-* components and gets timeout.

• OS Distro
  • Ubuntu 20.04
• JDK
  • openjdk-8, openjdk-11, openjdk-13, openjdk-16 (ubuntu bundled packages)

REPRODUCE PROCEDURE

Just download 0.4.2.0.zip, extract it and run startup-all.sh (with openjdk installation).

Set log_level of driver.conf (at least ) to DEBUG, and invoke start-all.sh or start-driver.sh, then see log/driver-boot.log.

ANALYSYS and SUGGESTED RESOLUTION

IMHO, the following errors in the log implies some inconsistencies between the COSBench bundled eclipse.equinox.launcher and Java environment.

Those errors disappeared and COSBench driver service started up normally after replacing eclipse.equinox.launcher jar file
from:
org.eclipse.equinox.launcher_1.2.0.v20110502.jar
to:
org.eclipse.equinox.launcher_1.6.300.v20210813-1054.jar
that is contained in 'eclipse-committers-2021-09-R-linux-gtk-x86_64.tar.gz' available at https://www.eclipse.org/

So, I would suggest upgrading the equinox.launcher jar to the latest (stable) one.

The below is a log file that I tried using openjdk-16.
