Ok. I made a much more deeper look, and consulted with Aph and Thomas, and this fix indeed looks wrong from all points of view.

To reduce it to (1,1),except obvious failures, seesm to no longer check the issue. Also it seems that for jdk 23 and up, the correct replacement are direct buffers - which  - feel free to correct me -  are well covered in jcstress,

Thus the correct fix seesm to be https://github.com/openjdk/jcstress/pull/159 or to remove the.

Closing this in  favour of  https://github.com/openjdk/jcstress/pull/159
