Using scala-2.9.1-final:
scala> ":yo:howdy:::".split(":")
res7: Array[java.lang.String] = Array("", yo, howdy)

scala> ":yo:howdy::: ".split(":")
res8: Array[java.lang.String] = Array("", yo, howdy, "", "", " ")

I expected res7 to be: Array("", yo, howdy, "", "", "")

Thanks.

Hi Glenn,

You should not:
http://download.oracle.com/javase/7/docs/api/java/lang/String.html#split(java.lang.String)
This is what you might want to check:
http://download.oracle.com/javase/7/docs/api/java/lang/String.html#split(java.lang.String,
int) with negative second parameter.
Hope this helps, gabor
