PROXY_FACTORY_CLASS_NAME

public static final String PROXY_FACTORY_CLASS_NAME

PROXY_FACTORY_SHARD_SIZE

public static final int PROXY_FACTORY_SHARD_SIZE

Adapters per factory shard method. Each case costs sixteen bytes of bytecode including its switch-table entry, so a shard stays under HotSpot's 8000-byte limit for JIT compilation, with room for DGM to grow.
