6940419: Bump the HS18 build number to 02 Summary: Update the HS18 build number to 02 Reviewed-by: jcoomes

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. As a result, updates from threads created during a marking cycle were never enqueued and never processed. The fix includes remaining a method from active() to is_active() for readability and naming consistency. Reviewed-by: ysr, johnc

6935839: excessive marking stack growth during full gcs Summary: process one item at a time from the objarray stack/queue Reviewed-by: apetrusenko, tonyp

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. Reviewed-by: ysr, tonyp, jmasa

6755988: G1: assert(new_obj != 0 || ... "should be forwarded") Summary: A TLAB became large enough to be considered a humongous object allowing multiple objects to be allocated in a humongous region, which violates a basic assumption about humongous regions. The changes ensure that TLABs cannot be regarded as humongous. Reviewed-by: iveresov, tonyp

4396719: Mark Sweep stack overflow on deeply nested Object arrays Summary: Use an explicit stack for object arrays and process them in chunks. Reviewed-by: iveresov, apetrusenko
