6930581: G1: assert(ParallelGCThreads > 1 || n_yielded() == _hrrs->occupied(),"Should have yielded all the .. Summary: During RSet updating, when ParallelGCThreads is zero, references that point into the collection set are added directly the referenced region's RSet. This can cause the sparse table in the RSet to expand. RSet scanning and the "occupied" routine will then operate on different instances of the sparse table causing the assert to trip. This may also cause some cards added post expansion to be missed during RSet scanning. When ParallelGCThreads is non-zero such references are recorded on the "references to be scanned" queue and the card containing the reference is recorded in a dirty card queue for use in the event of an evacuation failure. Employ the parallel code in the serial case to avoid expanding the RSets of regions in the collection set. Reviewed-by: iveresov, ysr, tonyp

# This shell script builds a vm.def file for the current VM variant.
# The .def file exports vtbl symbols which allow the Serviceability
# Agent to run on Windows. See make/windows/projectfiles/*/vm.def
# for more information.
#
# The script expects to be executed in the directory containing all of
# the object files.

# Note that we currently do not have a way to set HotSpotMksHome in
# the batch build, but so far this has not seemed to be a problem. The
# reason this environment variable is necessary is that it seems that
# Windows truncates very long PATHs when executing shells like MKS's
# sh, and it has been found that sometimes `which sh` fails.
