During testing of JSR 292's SPARC C2 port I found a couple of crashes which came from unfixed code-embedded oops.

EVALUATION http://hg.openjdk.java.net/jdk7/hotspot-comp/hotspot/rev/ed4f78aa9282

EVALUATION This can be triggered with ScavengeRootsInCode={1,2}.

SUGGESTED FIX Call fix_oop_relocations in CodeCache::scavenge_root_nmethods_do after oops may have been updated.
