I could not understand how this could be if the tests and other code
were unchanged, so I applied the ASM-only patch and investigated the
first failure running nasgen. And of course the problem is the
NestHost/NestMembers attributes! We modified our internal version of ASM
to add nestmate support, but of course this update removes that and
replaces it with the official support. But the official support is only
enabled for ASMv7 so we must update all users of ASM to request version 7.
