I read it as meaning "we don't enable the helpers, because without serviceability agent there's no point in having them. Which is very far from the truth.

As you might expect, SA tests don't run on s390:


   TEST                                              TOTAL  PASS  FAIL ERROR   
   jtreg:test/hotspot/jtreg/serviceability/sa            0     0     0     0   


I don't think they're specificially excluded on s390.
