This appears to be a problem with incorrect register kills in the StringUTF16.compress intrinsic.

No. Lets fix it in JDK 13. It will be forward ported into JDK 14 automatically.

May be following could be the next steps here ! - Change Fix Version here for 8227034 to 14, - close this as duplicate of 8226771 next Graal-Update - then create a new backport here for 13 and do as separate fix for 13 ?

This should be fixed in JDK 13 as separate fix. We will not push any more 'Update Graal' into JDK 13. I see that the fix is already in upstream Graal: https://github.com/oracle/graal/commit/14b7ebd4f3f0ebc56ee33a091a8f860f3271f521
