      The direct code that's acquiring the lock out of order belongs to GC,
      but that collect() call is happening in response to an AdapterBlob::create()
      and we get there from method linking and link resolution. I think there's
      more Runtime code involved here than GC code so I'm starting this bug
      off in hotspot/runtime for initial triage.
