What steps will reproduce the problem?
./scripts/inference.py --checker ostrusted.OsTrustedChecker --mode roundtrip-typecheck --log-level FINE --solver checkers.inference.solver.MaxSat2TypeSolver bar.java
Contents of bar.java:
import ostrusted.quals.OsTrusted;
class bar {
void foo(@OsTrusted String @OsTrusted [] s){}
}
What is the expected output? What do you see instead?
Expect inference and typechecking to complete without errors. See an IllegalArgumentException instead (stack trace below).
