Bad symbolic reference. A signature compilation error

[chungonn]

The code compiles in Scala 2.13.1 but emits error on dotty 0.24.0-RC1

Minimized code

build.sbt

val dottyVersion = "0.24.0-RC1"

lazy val root = project
  .in(file("."))
  .settings(
    name := "dotty-simple",
    version := "0.1.0",

    scalaVersion := dottyVersion,

    libraryDependencies ++= Seq(
      "org.threeten" % "threeten-extra" % "1.5.0",
      "com.novocode" % "junit-interface" % "0.11" % "test",
      "ch.epfl.lamp" %% "dotty-staging" % scalaVersion.value
    )
  )

code

def toMyInterval(value: String): org.threeten.extra.Interval = org.threeten.extra.Interval.parse(value)

object Interval310 {
  def main(args: Array[String]): Unit = {
    println("hello world")
  }
}

Expectation

[griggt]

Alternative minimization without the threeten-extra dependency:

foo/Foo.java

package foo;

import org.joda.convert.FromString;

public final class Foo {
    @FromString
    public static Foo parse(CharSequence t) { throw new UnsupportedOperationException(); }
}

test.scala

import foo.Foo

object Test {
  val bar = Foo.parse("")
}

$ javac -classpath $JARS/joda-convert-2.2.1.jar foo/Foo.java

# note: joda-convert-2.2.1.jar not on dotc classpath
$ dotc test.scala

This is a duplicate of #8554 which is fixed by #9096.

@smarter Do you feel that the test you wrote for #9096 is sufficient to close this issue?

[smarter]

Yeah seems like this is the same.
