File src/objects.cc (right):
http://codereview.chromium.org/3028019/diff/1/4#newcode2117
src/objects.cc:2117: class NormalizedMapCache {
: public AllStatic ?
Also, please have public: section before private:.
http://codereview.chromium.org/3028019/diff/1/4#newcode2154
src/objects.cc:2154: return index & 0xFF;
