Stacked on #412.

Description

When nothing is known about the receiver's state (e.g. a parameter with no state refinement), the error used to say only that no state information is known. For classes with a state machine, it now lists the constructors and the calls that lead to a state allowing the failing call, each with the states it is called from.

Classes without a state machine keep the previous general hint.

Example

static void use(File f) {
    f.read(); // read() needs open
}
 --> The state of f is unknown here. To get it to open, use: f.open() (from created)

Type of change

  • New feature

Checklist

  • Added tests: ErrorStateHintUnknownState. TestStateHints also checks that a class without @StateSet keeps the general hint.
  • mvn test passes locally

constructors and the calls, with the states they are made from, that
lead to a state allowing the failing call.
