Java exception creating new objects in Eclipse 2023-09 and latest ADT

[matt]

New install of Eclipse Version: 2023-09 (4.29.0) Build id: 20230907-1323 and ADT 3.36.2. Using JRE SAPMachine 21.

I can create objects in $TMP, but can't create anything in a package. I get the message:

java.lang.reflect.InvocationTargetException

The same error occurs whether normal ABAP project or Cloud.

Log file:

Just did new install of 2023-06 with latest ADT and latest SAP Machine... same problem.

Tomorrow I'll try to revert the SAP Machine.

[matt]

With 2023-09, latest ADT and SAP Machine 17 - it worked. I've reported the issue on the SAP Machine github.

Update: But it seems most likely it's an ADT incompatibility, somewhere in the bit that prompts for a transport, since $TMP works.

Final response from SAP Machine Github.

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.
