In src/hotspot/share/prims/jvmtiTagMap.cpp, JvmtiTagHashmapEntry::equals(..) we need an equals barrier.
In the same file, in the hash() function, it's converting the plain oop to an integer. The oop should better be resolved to a stable value there.
Finally, in jvmtiExport.cpp, in JvmtiObjectAllocEventMark, we're missing an CH::obj_size() call instead of the 'raw' obj->size(), which is needed to make size reported by the callback and by GetObjectSize() consistent.
