The problem shows up in the JUnit compiler tests used for the backend. To reproduce, add a file test/junit/scala/tools/nsc/backend/jvm/opt/ResidentFail.scala:

package scala.tools.nsc
package backend.jvm
package opt

import org.junit.runner.RunWith
import org.junit.runners.JUnit4
import org.junit.Test
import CodeGenTools._

object ResidentFail {
  val compiler = newCompiler()
}

@RunWith(classOf[JUnit4])
class ResidentFail {
  import ResidentFail._

  @Test
  def test1(): Unit = {
    compile(compiler)("class B", List(("public class A { }", "A.java")))
  }

  @Test
  def test2(): Unit = {
    compile(compiler)("class A")
  }
}

Fails when running both tests, works when running each test separately.
