subject AbstractMethodError for ::.apply at runtime
code 
oabstract class MySeq extends Seq[String] {
  def theSeq: Seq[String];
  def apply(i:int) = theSeq.apply( i );
  def length       = theSeq.length;
  def elements     = theSeq.elements;
}

object Foo extends Object with Application {
  val reviews = new MySeq { val theSeq = List("a","b") };
  reviews(0);

}
what happened 
fails at runtime with an AbstractMethodError.

emir@lamppc31:/tmp>nsc -d . test5.scala
emir@lamppc31:/tmp>ns -cp . Foo
Exception in thread "main" java.lang.AbstractMethodError: scala.$colon$colon.apply(Ljava/lang/Object;)Ljava/lang\
/Object;
        at MySeq.apply(test5.scala:3)
        at Foo$.(test5.scala:8)
        at Foo$.(test5.scala)
        at Foo.main(test5.scala)
what expected no AbstractMethodError exception.

I could reproduce it at first, but after recompiling the libraries the problem is gone. It might be a script problem that it got some old version of the class ::. I marked it as not reproducable. Burak, you might want to re-awaken the bug if you notice the problem again. -- Martin
