I guess that's me. I didn't know that we need to do 3 passes. We just do
the first 2 passes.
(I haven't checked the source code, so it may already be done like
this.)

Subject: Re: [scala-user] scalac and javac

The scalac compiler does not compile Java source to bytecode. It
merely parses Java source in order to get the type information it
needs to compile the Scala source that depends on the Java source.
The recommended approach is to use a three-pass compile. Run scalac
once on *.scala and *.java files to produce Scala *.class files. Run
javac once on *.java files with Scala *.class files in the classpath
to produce Java *.class files. Run scalac again with the real Java
*.class files in case the Scala compiler made any incorrect
assumptions about them in the first pass.
This three-pass system is recommended but not necessary. Some people
have reported successful compilations with just two passes.

I had to add a javac just as well, to compile those.
Is this the correct approach?
<scalac scalacdebugging="true" srcdir="src"
destdir="bin">
<classpath refid="build.classpath" />
</scalac>
<javac srcdir="src" destdir="bin">
<classpath refid="build.classpath" />
</javac>
