[~coleenp]This needs to be fixed as part of the redo of JDK-8366341. It can't be done before or after.
29-08-2025
We don't really want this closed because we want to reintegrate JDK-8366341 once this is fixed.
29-08-2025
Re-Closed as Duplicate

Fixed by backing out in https://bugs.openjdk.org/browse/JDK-8366341 (switched resolution from Fixed to Delivered)

We see similar failures in our CI in test sun/tools/jhsdb/JShellHeapDumpTest.java .

It seems like when _immutable_data is null, the returned Address is the Java null object, when it probably should be Address(0).

Same issue with test: sun/tools/jhsdb/JShellHeapDumpTest.java
