I have a jazz team server runnning
And an Eclipse IDE for Enterprise Java and Web Developers (includes Incubating components)
Version: 2021-03 (4.19.0), 
Using jdk-16.0.2 library
  

When, inside Eclipse, through Team Artifacts View -> Create a Repository Connection, I try to create a jazz repository connection, It connects (user and password are ok), but I get the following message:

Could not get value of field private transient sun.util.calendar.BaseCalendar$Date java.util.Date.cdate in 2021-04-22 10:58:57.95

 Add these two lines to the Eclipse.ini


--add-opens=java.base/java.lang=ALL-UNNAMED
--add-opens=java.base/java.util=ALL-UNNAMED

I had the same problem with Eclise 2021-09 with JRE 17 and the p2 repo for EWM 7.0.2 client.
When trying to connect to a Jazz repo I got the error message 
Could not get value of field private transient sun.util.calendar.BaseCalendar$Date java.util.Date.cdate in 2021-09-29 18:08:52.74

When using the eclipse installer and select the JRE version 16 instead 17 a repository connection is successful against EWM 7.0.2.

 Thanks for the help. I was banging my head against a brick wall on this one.

Please download the vanilla Eclipse client for the version of your CCM server e.g. the plain zip version. Try to connect to your repository using that vanilla Eclipse client using the IBM Java that is included in the download.

I resolved downloading the eclipse LUNA client, (2014)  running against jazz team server that cames with RTC702.

It seems that there is some incompatibility with latest version of Eclipse.
Anyway i See you advice was the right direction (I change eclipse cliente before I read your answer...)

For the extensions workshop I use Neon 4.6 from 2016.

As of today only versions up to 4.15 are supported for EWM/RTC

Ran into same problem following the lab

trick is to be ABSOLUTELY sure you are grabbing the OLDER eclipse Luna... which is buried under "Older Releases"

Edit: to add here is the link in case others hit this problem:

If in doubt try the vanilla EWM Client that is available as a plain zip file. The reason why the workshop uses a P2 install is, that in the beginning the EWM/RTC Plain Zip vanilla client lacked some Eclipse Plugin Development Environment capabilities. This is no longer the case. Also check the release notes, for 7.02 development it appears that Eclipse up to version 7.14 works. Make sure to use Java 8 - which the workshop actually makes sure you do.

 Hi, Below are the combinations of Java/Eclipse clients versions I have tried


Eclipse 2019-06 (supported according IBM) - Java 8 - EWM works as expected
Eclipse 2021-09 (Not supported according to IBM) - Java 8 - Will not start (requires Java 11)
Eclipse 2021-09 -Java 11 - EWM plugin starts and appears to work as epected - Some eclipse plugins (Wild Web Developer do not work.. require Java 17+)
Eclipse 2021-09- Java 14 - EWM plugin starts and appears to work as epected - Some eclipse plugins (Wild Web Developer do not work.. require Java 17+)
Eclipse 2021-09 - Java 15-17 - EWM Plugin will not connect to server - Other plugins now work :(

Hoping IBM fixes the java compatibilty issue.. it is likely a really simple fix to avoid using the cdate call which appears to be be deprecated now.. 

Hope that is of some use to people.

Pete

 Try adding --add-opens=java.base/java.util=ALL-UNNAMED to eclipse.ini

Works for me. Could you past the stack trace from the error message please?

Ok that should explain it.

module java.base does not "opens java.lang" to unnamed module 

You need to add a line that I already had in my eclipse.ini I guess.
Please also add:

--add-opens=java.base/java.lang=ALL-UNNAMED
