scala-javautils

Starting with version 2.7.2, Scala added an experimental feature (which will no longer be experimental as of 2.8.0) called Manifests that allow you to selectively reify erased types. See this blog post for more: http://www.scala-blogs.org/2008/10/manifests-reified-types.h... This, combined with specialization (compiling primitive-specialized versions of code with generic types to improve performance of, for example, using function types on primitive collections) will make it easier to write performant, numeric code in Scala than in any other JVM language (up to the limits of the JVM, of course). The NLP communities at Stanford and Berkeley, which do a fair amount of machine learning, have a long history of working in Java (http://nlp.stanford.edu/software/, http://nlp.cs.berkeley.edu/Main.html#Software) and have recently started using Sca

Scala/Java integration will always be somewhat of a problem, that requires thought and effort to get right. Any default way of converting between classes will leave some people going "WTF?". Jorge Ortiz's scala-javautils[1] can be helpful. Googling for these utils will lead to some blogposts discussing the problems of fully automatic conversion.
