> Please note: I am unsure whether this is a bug within the Scala compiler or less than
perfect Java SE 6 compatibility on Harmony's part.
> To reproduce the bug/incompatibility compile WeakHashMap.scala from the Scala library
(version 2.8.0.RC3) against the Apache Harmony 6.0M1 JRE, with CLASSPATH set to the .jars
in the Harmony distribution:
> > ./bin/scalac -version
> Scala compiler version 2.8.0.RC3 -- Copyright 2002-2010, LAMP/EPFL
> > ./bin/scalac -javabootclasspath $CLASSPATH ../scala/src/library/scala/collection/mutable/WeakHashMap.scala

> error: error while loading WeakHashMap, Missing dependency 'class java.util.Map$Entry',
required by /usr/lib/harmony-6.0/jdk/jre/lib/boot/luni.jar(java/util/WeakHashMap.class)
> error: error while loading AbstractMap, Missing dependency 'class java.util.Map$Entry',
required by /usr/lib/harmony-6.0/jdk/jre/lib/boot/luni.jar(java/util/AbstractMap.class)
> error: error while loading Hashtable, Missing dependency 'class java.util.Map$Entry',
required by /usr/lib/harmony-6.0/jdk/jre/lib/boot/luni.jar(java/util/Hashtable.class)
> three errors found
> For some reason, scalac, the Scala compiler, is unable to track down the Entry class.
I suspect that there is some subtle difference between Harmony's classes and those of the
Sun JDK.
