java.lang.VerifyError on RichInt

[Bill Atkins]

I just upgraded to Scala 2.9.0 (and the latest 2.9.0-compatible ScalaQuery). When I try to insert a row into a ScalaQuery-mapped table, I get the following error:

Exception in thread "main" java.lang.VerifyError: class scala.runtime.RichInt$$anon$2 overrides final method foreach.(Lscala/Function1;)V

    at scala.runtime.RichInt.until(RichInt.scala:25)
    at org.scalaquery.ql.basic.BasicInsertBuilder.f$1(BasicInsertBuilder.scala:32)
    ....

The snippet in ScalaQuery that causes this is in BasicInsertBuilder.scala:

      case p:Projection[_] =>
        for(i <- 0 until p.productArity)
          f(Node(p.productElement(i)))
 
but I don't see any problem there.

The RichInt.until implementation in question is a bridge method:

      @bridge
      def until(end: Int): Range with Range.ByOne = new Range(self, end, 1) with Range.ByOne

Does anyone know what would cause this? If this is more a ScalaQuery issue than a 2.9.0 issue, let me know and I can redirect my question to the ScalaQuery mailing list.

Thanks,
Bill

https://lampsvn.epfl.ch/trac/scala/ticket/4575
"java.lang.VerifyError: class scala.runtime.RichInt$$anon$1 overrides final method foreach.(Lscala/Function1;)V"

[Bill Atkins]

I see - thanks!

Just to note that Scala moved from trac to jira so the link to the bug is now:
https://issues.scala-lang.org/browse/SI-4575?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Looks like odersky has fixed this compiler bug, but I do not know if such a fix has been released. I am seeing the same runtime exception with Glassfish:

The bug was fixed in trunk, but no release includes it yet. What
version of Scala did you use?

Best,
Ismael

[Robbie Coleman]

I was using the full release of 2.9.0, but I do see issues with some of our dependencies like lift json and a couple others that have yet to release even a snapshot version built against 2.9.0.

Thanks for the update @Ismael.

That has the issue, so it's indeed expected to fail.

lift-json has released a snapshot version built with 2.9.0 a couple of days ago.

Best,
Ismael

[martin odersky]

We will push out a maintenance release of 2.9 shortly that contains a fix for this problem as well as a couple of others.

FYI, just downloaded scala-2.9.0.1 and am getting
    java.lang.NoSuchMethodError: scala.runtime.RichInt.until(I)Lscala/collection/immutable/Range$ByOne;
    at Main$$anon$1$$anonfun$2$$anonfun$apply$4.apply(OverallDelayInfo.scala:112)
at the for-loop line below

        val in = new java.io.FileInputStream(file)
        var lines = Source.fromInputStream(in).getLines.toArray
        //println(file.getName + " has " + lines.length + " lines.")
        in.close
 
        val inHeaderRow = lines(0).split(",")

       for(i <- 0 until inHeaderRow.length)  // exception is thrown at this line

... So I'm reverting to 2.8.0.final.

[Naftoli Gugenheim]

Did you do a clean build?

[Sue Hinton]

My code "build" should be clean, as I use a commandline scripting mechanism to run, i.e.,
>  scala MyScript.scala <input params>

The build of scala was downloaded from the web into its own directory, and is used exclusively, so it should be clean.

[James Moore]

I think I'm seeing the same thing with 2.9.1 and 2.9.2.  The error I get is:

(using scala-2.9.2.r25964-b20111108042542)

[error] (run-main) java.lang.VerifyError: class com.restphone.IsList$ overrides final method canEqual.(Ljava/lang/Object;)Z

(full trace at https://gist.github.com/1350811)

If I rebuild with scala-2.10.0.r25972-b20111109023956 I don't see the problem.

[James Moore]

Code at  https://s3.amazonaws.com/teenstarter/Deleteme3.tar.bz2.  It should run with sbt run.  (Warning: the project isn't finished, readable code.  It's a project that I use as a scratch area for experiments.  However, it should repro the stack dump repeatably.)
