  }
}
what happened

Exception in thread "main" java.lang.AbstractMethodError: scala.collection.mutable.HashMap$class.entryKey(Ljava/\
lang/Object;)Ljava/lang/Object;
	at scala.collection.mutable.HashMap$class.addEntry(sources/scala/collection/mutable/HashMap.scala:65)
	at scala.collection.mutable.HashMap$class.update(sources/scala/collection/mutable/HashMap.scala:34)

seems related to bug#37

The last update of AsSeenFrom fixed the AbstractMethodError problem. The program now runs correctly with the compiler, but with this interpreter, it raises the following error: 

Exception in thread "main" java.lang.ArrayStoreException
        at scala.runtime.RunTime.oarray_set(RunTime.java:589)
        at scala.collection.mutable.HashMap$class.initTable(HashMap.scala:112)
        at scala.collection.mutable.HashMap$class.(HashMap.scala:47)
        at Test.main(test.scala:6)
but this is probably another bug.
