SAP Machine 21, Eclipse 2023-09, ADT - exception

[matthewdjb]

See here: https://answers.sap.com/questions/13982417/java-exception-creating-new-objects-in-eclipse-202.html

New install of Eclipse Version: 2023-09 (4.29.0) Build id: 20230907-1323 and ADT 3.36.2. Using JRE SAPMachine 21. To replicate the problem, try to create any repository object (E.g. a class) on a SAP System (cloud or on premise), in any package except $TMP.

I get the message:

java.lang.reflect.InvocationTargetException

I got the same issue on Eclipse 2023-06. Reverting to SAP Machine 17 resolved the issue, so I'm pretty sure it's a SAP Machine 21 issue.

Hi, is there some statement from Eclipse side that it is already fully compatible with JDK21 ?

...Using JRE SAPMachine 21.

Is the problem also visible with SAPMachine 21 JDK ?

[MBaesken]

btw. I noticed here
https://marketplace.eclipse.org/content/java-21-support-eclipse-2023-09-429
that some additional feature needs to be installed for JDK21 compatibility - are you aware of this feature ?

This probably doesn't have to do with the problem here. The link is what you need when you want to use Java 21 features in Eclipse IDE for Java.

@matthewdjb Assuming that Eclipse itself runs on JDK 21, I guess this is an issue in ADT. I'm currently trying to connect with the colleagues to find out more...

[matthewdjb]

Yes, I meand JDK 21. Sorry about that.

If it's ADT, I think it's probably somewhere in the bit where it prompts you for a transport, as it works with $TMP.

[sratz]

The problem is within ADT (more precisely: within the URI template library dependency used by ADT).

We are working on this.

Until this is resolved, ADT cannot be used with JDK 21.

[RealCLanger]

Thanks @sratz. With this, I'm closing this ticket. Maybe you can add some further reference here once you have some record for this issue, e.g. an SAP Note.

[sratz]

ADT 3.38 (released October 25, 2023, https://me.sap.com/notes/3391753) is now compatible with Java 21.

[matthewdjb]

Great stuff. Thank you!
