[jdk25u-dev] RFR: 8377811: G1: Optional Evacuations may evacuate pinned objects

[Ivan Walulya]

Hi,

Please review this patch which ensures that the pinned region attribute is correctly set when registering old regions for evacuation. Old regions that may contain pinned objects require special handling during evacuation so that "pinnable objects" remain in place while other objects may still be evacuated. This change propagates the pinning information correctly to enable that specialized evacuation behavior.
