java.lang.NoClassDefFoundError: Could not initialize class java.util.Currency

[Brett Hoerner <br...@bretthoerner.com>]

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"
