RFR: 8373695: G1: Using a value near integer max for ActiveProcessorCount causes fatal crash

Tue Dec 16 17:27:57 UTC 2025

G1ConcRefinementThreads default value depends on ParallelGCThreads which in turn may depend on ActiveProcessorCount. These have different ranges that are valid. Patch will ensure argument setup code never try to assign a value larger than what G1ConcRefinementThreads expects.
