VerifyError: current frame type not assignable to stack map frame type #11294

Closed odd closed 5 years ago

odd commented 5 years ago

While working on adding benchmarks for the new 2.13 collections using JMH, the following error has been encountered:

The code causing the error is:

class StackMapError {
  @org.openjdk.jmh.annotations.Param(scala.Array(""))
  var notUsed: String = _

  def f() = {
    if ("x" == "y") List.from(List(1))
    else collection.immutable.ArraySeq.from(List(1))
  }
}

It does not seem to matter which immutable seq sub types that are used; the error occurs as long as immutable.AbstractSeq is a common super type. Using a mutable seq like the following code does not cause the error: 

class StackMapError {
  @org.openjdk.jmh.annotations.Param(scala.Array(""))
  var notUsed: String = _

  def f() = {
    if ("x" == "y") List.from(List(1))
    else collection.mutable.ArraySeq.from(List(1))
  }
}

The branching mechanism doesn't matter, the following code causes the same error:

class StackMapError {
  @org.openjdk.jmh.annotations.Param(scala.Array(""))
  var notUsed: String = _

  def f()= {
    "x" match {
      case "y" => List.from(List(1))
      case _ => collection.immutable.ArraySeq.from(List(1))
    }
  }
}

Tested on JVM: 1.8.0_181, 1.8.0_192 Graal, 11/18.9 Scala: 2.13.0-M5 JMH: 1.21

@smarter suggested I ping @lrytz for this issue.

odd commented 5 years ago

The same problem as when calling from also occurs when calling empty. The following code causes the error:

  def f()= {
    "x" match {
      case "y" => List.empty[Int]
      case _ => collection.immutable.ArraySeq.empty[Int]
    }
  }

The following code does not cause the error:

  def f()= {
    "x" match {
      case "y" => List.empty[Int]
      case _ => collection.mutable.ArraySeq.empty[Int]
    }
  }
lrytz commented 5 years ago

@odd I couldn't reproduce this by just compiling the method in a separate source file. Could you push a branch somewhere with your changes and let me know what to run to trigger the error?

odd commented 5 years ago

@lrytz I have created https://github.com/odd/scala-stackmaperror, please have a look and see if you can reproduce it there (if not is probably something wrong with my local 2.13.0-M5 jar or something like that...).

lrytz commented 5 years ago

I can reproduce the problem. I'm having a hard time nailing it down though. The error message is

Type scala/collection/immutable/List (current frame, locals[1]) is not assignable to scala/collection/immutable/AbstractSeq

Indeed the stack map frame says

   L3
   FRAME FULL [Failures scala/collection/immutable/AbstractSeq java/lang/String] []

and one of the branches jumping to L3 stores an scala/collection/immutable/List into local variable 1.

The Scala version is set to 2.13.0-M5, and looking at the classfile (unzip /Users/luc/.ivy2/cache/org.scala-lang/scala-library/jars/scala-library-2.13.0-M5.jar scala/collection/immutable/List.class) I get

public abstract class scala/collection/immutable/List extends scala/collection/immutable/AbstractSeq ...

It seems the error is thrown when jmh is processing classfiles. Running with sbt --debug, I see

Annotation generator had thrown the exception.
java.lang.VerifyError: Inconsistent stackmap frames at branch target 69
...

My wild guess is that there's a different scala-library version on the classpath. I just don't know right now how to debug this further. Maybe @ktoso can help us out?

adriaanm commented 5 years ago

@dwijnand would you have some spare cycles to diagnose / verify Lukas's hypo that the underlying issue is conflicting scala-library jars on the classpath?

dwijnand commented 5 years ago

Hmm, no, and not enough prior knowledge of sbt-jmh or jmh to backfill the lack of cycles.

Another wild guess (less probably) is the scala.List rewrite in the compiler?

adriaanm commented 5 years ago

I can also repro by invoking the given task, but can't repro it programmatically from the console (to further diagnose what the classpath is etc):

I got the values used by doing show etc, but i must be missing some aspect of how the forked classpath is set up. I can't do show failures / Jmh / fullClasspathAsJar without getting the verify error already, so not sure where to look for that

Ok, I convinced myself it's a classpath problem with the plugin. It has the scala 2.13.0-M5 library as well as the 2.12.7 jars on the classpath.

Painstakingly recreating the classloaders yields:
