6935821: G1: threads created during marking do not active their SATB queues Summary: Newly-created threads always had the active field of their SATB queue initialized to false, even if they were created during marking.

The fix includes remaining a method from active() to is_active() for readability and naming consistency. Reviewed-by: ysr, johnc

6921710: G1: assert(new_finger >= _finger && new_finger < _region_limit,"invariant") Summary: If CM task was aborted while scanning the last object of the specified region and the size of that object is equal to bitmap's granularity then the next offset would be equal or over the region limit which is exactly what the assertion states.
