Field Detail

collectorContext

public Selected.Collector collectorContext
The collector context to be used by the given thread. Only collector threads have collector contexts.

NOTE: if we have N processors and we're running with a concurrent collector, we will have 2*N collector contexts - N for the stop-the-world collector threads, and N for the concurrent collector threads.
