review (XS) for 6849574: VM crash using NonBlockingHashMap (high_scale_lib)

[Vladimir Kozlov]

Tom,

In c1_LIRGenerator.cpp you changed code to do imprecise card mark on object.
What happens if the object is large and the field is outside of imprecise card mark?

Also can you explain the original comment there (could be related to the first question)?
!     // Precise cardmarks don't work

thanks,
Vladimir
