I got a scenario description.

New PC (win 2025 or win 11), new openJDK (OpenJDK25U-jre_x64_windows_hotspot_25.0.1_8) in connection with netx.jar does not work. Test with OpenJDK21U-jre_x64_windows_hotspot_21.0.9_10 works as expected. Tested against a 11.40 commserve

I tested it with with a windows 2019 box.OpenJDK25U

command java –jar netx.jar

target is a 11.36.72 machine

connection Ok, but browser on the left site does not work.! (classic view)

Cannot start jobmanager!

Same test with OpenJDK21U shows no issues.

Checked doku

Opening the CommCell Console Using the Command Line Interface

  • The minimum JRE version on the computer must be the same major version that Commvault deploys (or a newer minor/patch level).

It should work

There are many options for the java command. Which options are to use with  OpenJDK25U to get the Commcell Console work as before?

I also ran into this issue where the Commcell Console didn’t have the left side and couldn’t open the Job Controller. I thought it was Java being updated on my system but it turns out that the CommServe had Windows updates installed and had  the BranchCache service enabled and running. After stopping this service and restarting Tomcat on the CommServe, the Commcell Console functionality returned. I’m not sure if this would apply to your situation though.

I expanded my test by restarting the services on Commserve. Machine with OpenJDK25U was rebooted before test. Result was the same as described before and I need the taskmanager to end the session. 

next test: deinstall OpenJDK25U. Install OpenJDK21U. Reboot Testmachine.

Again java –jar netx.jar

Commcell Console works as expected. It can be closed without taskmanager. there was no need to recycle the services on Commserve again.

My recap at the moment.

Do not use OpenJDK25U if you want to use Commcell Console. Tested with 11.36 and 11.40.
