subject [contrib #1] overridden methods ("inheritance does not work")
code 
object testBuf {
  class mystream extends java.io.BufferedOutputStream(new java.io.FileOutputStream("/dev/null")) {
    def w( x:String ):Unit = {
      val foo = new Array[byte](2);

      // write( byte[] ) is defined in FilterOutputStream, the superclass of BufferedOutputStream
      super.write( foo ); // error

      super.write( foo, 0, foo.length ); // this works however
    }
  }
}
what happened 
/home/hejira> scalac -d /tmp /tmp/testBuf.scala
/tmp/testBuf.scala:7: type mismatch;
 found   : scala.Array[scala.Byte]
 required: scala.Int
      super.write( foo ); // error
                   ^
one error found
what expected no error

This is indeed not normal behaviour is it ? It was shortly discussed in a Scala meeting. All names, also overridden ones of a Java class, should be visible to Scala, no ?

The (open) question is whether we can change our overloading behavior to more closely resemble Java's.

I fixed the compiler to accept this case, by adding inherited overloaded methods.
