Jordi:
I think I need more information.
You said you are running as a service, and from the messages you listed, it appears that you are running Linux.
I don't see a –D parameter in any of the sh files in the CTP/linux directory. Can you look at the file that you are running to start your service and see if it contains a –D parameter? If so, remove it and see what happens.
I assume that your service starts CTP by running the Runner.jar program. That program only includes the –D parameter if the Java on which it is running is version 8 or less. Is it possible that your CTP is out of date?

I have recently upgraded the OS of a machine hosting a CTP service and along with the OS, Java also got updated. Now I am at version 11. Attempting to start CTP as a service I get into the following issue,
Feb 9 13:00:19 strmaragall01 systemd[1]: Started CTP Service. Feb 9 13:00:20 strmaragall01 ctp-wrapper.sh[19460]: Starting CTP Feb 9 13:00:20 strmaragall01 ctp-wrapper.sh[19460]: java -Xmx2048m -Xms2048m -Djava.ext.dirs=null -jar libraries/CTP.jar Feb 9 13:00:20 strmaragall01 ctp-wrapper.sh[19460]: stderr: Error: Could not create the Java Virtual Machine. Feb 9 13:00:20 strmaragall01 ctp-wrapper.sh[19460]: stderr: Error: A fatal exception has occurred. Program will exit. Feb 9 13:00:20 strmaragall01 ctp-wrapper.sh[19460]: stderr: exit Feb 9 13:00:20 strmaragall01 ctp-wrapper.sh[19460]: stdout: -Djava.ext.dirs=null is not supported. Use -classpath instead. Feb 9 13:00:20 strmaragall01 ctp-wrapper.sh[19460]: stdout: exit Feb 9 13:00:20 strmaragall01 ctp-wrapper.sh[19460]: Exit: code 1 Feb 9 13:00:21 strmaragall01 ctp-wrapper.sh[19460]: Runner: exit. Seems like after Java version 8 the command line directive -Djava.ext.dirs was deprecated and the recommendation to use -classpath instead. In the past, java.ext.dirs was used to instruct the JRE from where to load additional class and jar files.
I see 2 options, (a) install Java 8 and use it for running CTP (b) update CTP and see if it takes care of such deprecation and supports newer versions of Java
@johnperry, do latest versions of CTP support Java 9+ or still require Java 8 to run? What would your advice be here?
Thanks

Thanks for your help John.
Yes, my CTP instance is rather outdated,
CTP Build: 2018.01.26 at 11:28:26 CST on Java 1.7
To clarify, I created a while ago a systemd daemon service for running CTP in a Linux system in a stable-ish mode. That's been working fine for some time and basically runs as follows (see processes),
/usr/bin/java -jar /opt/ctp/bin/Runner.jar start
\_ java -Xmx2048m -Xms2048m -Djava.ext.dirs=/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext:/usr/java/packages/lib/ext -jar libraries/CTP.jar
As you can see above, is the Java process spawned by Runner.jar
the one with such -D
parameters. I am afraid I cannot do much to remove them.
Jordi:
I think if you just remove the text
-Djava.ext.dirs=/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext:/usr/java/packages/lib/ext
from the start command, it will run.
