// A PostDepsMutator pass that enforces total order on non-updatable system server jars. A total
// order is neededed because such jars must be dexpreopted together (each jar on the list must have
// all preceding jars in its class loader context). The total order must be compatible with the
// partial order imposed by genuine dependencies between system server jars (which is not always
// respected by the PRODUCT_SYSTEM_SERVER_JARS variable).
//
// An earlier mutator pass creates genuine dependencies, and this pass traverses the jars in that
// order (which is partial and non-deterministic). This pass adds additional dependencies between
// jars, making the order total and deterministic. It also constructs a global ordered list.
