Shenandoah: allow earlier recycle of trashed regions during concurrent root processing

    XMLWordPrintable

    Details

    • Subcomponent:
      gc

      b19

      Description

      Currently, we disable recycling trashed regions during concurrent root processing phase.

      In fact, we only need to disable recycling while processing weak roots/performing class unloading, and enable it for evacuating and updating remaining roots.

      This should help to mitigate the chances of allocation failures, that can result STW degenerated GC.
