Yes, a fair point though. We did not want the test failures cause noise for SPARC but i guess different CPU platforms might have different test policies in this regard.

Hmm... it seems the following incantation might work:

  * @requires os.arch != “sparc"

if someone else can confirm that is sufficient to avoid execution on SPARC platforms then perhaps Dmitry can update his patch and then there is no conflict.

Otherwise i am sure some polite “you go first, no you first” arrangement can be reached :-)
