// additions. Would be nice to have in one place.
/** A collection of decorators that allow converting between
* Scala and Java collections using `asScala` and `asJava` methods.
*
* The following conversions are supported via `asJava`, `asScala`
*
* - `scala.collection.Iterable` <=> `java.lang.Iterable`
* - `scala.collection.Iterator` <=> `java.util.Iterator`
* - `scala.collection.mutable.Buffer` <=> `java.util.List`
* - `scala.collection.mutable.Set` <=> `java.util.Set`
* - `scala.collection.mutable.Map` <=> `java.util.Map`
* - `scala.collection.mutable.concurrent.Map` <=> `java.util.concurrent.ConcurrentMap`
*
* In all cases, converting from a source type to a target type and back
* again will return the original source object, e.g.
* {{{
* import scala.collection.JavaConverters._
*
* val sl = new scala.collection.mutable.ListBuffer[Int]
* val jl : java.util.List[Int] = sl.asJava
* val sl2 : scala.collection.mutable.Buffer[Int] = jl.asScala
* assert(sl eq sl2)
* }}}
* The following conversions are also supported, but the
* direction from Scala to Java is done by the more specifically named methods:
* `asJavaCollection`, `asJavaEnumeration`, `asJavaDictionary`.
*
* - `scala.collection.Iterable` <=> `java.util.Collection`
* - `scala.collection.Iterator` <=> `java.util.Enumeration`
* - `scala.collection.mutable.Map` <=> `java.util.Dictionary`
*
* In addition, the following one way conversions are provided via `asJava`:
*
* - `scala.collection.Seq` => `java.util.List`
* - `scala.collection.mutable.Seq` => `java.util.List`
* - `scala.collection.Set` => `java.util.Set`
* - `scala.collection.Map` => `java.util.Map`
*
* The following one way conversion is provided via `asScala`:
*
* - `java.util.Properties` => `scala.collection.mutable.Map`
*
* @since 2.8.1
