This is new.

I think you are referring to the following comment in tsanOopMap.hpp:

"// Oop size must be cached, as it is unsafe to call size() after reference is
// collected."

I added following in tsanOopMapTable.hpp:

"// The oop sizes are saved in the table because we need to
// use the size information when notify TSAN about an freed object."
