java.lang.NoClassDefFoundError: Could not initialize class java.util.Currency
Has anyone ever seen something like this on the Kafka (0.7.2) broker side?
I'm running JDK7, and that class most definitely exists

Once this started it just spammed non-stop (for everything each producer
sent to the box, I think) and Kafka was totally wedged. I bounced and it
came back online immediately.

# Line that raises the issue in Log.scala:
val nf = NumberFormat.getInstance()

# An SBT console on that box:
scala> import java.util.Currency
import java.util.Currency

scala> import java.text.NumberFormat
import java.text.NumberFormat

scala> val nf = NumberFormat.getInstance()
nf: java.text.NumberFormat = java.text.DecimalFormat@674dc

# Java on that box
$ java -version
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)
