I've written a helper function to generate one-off randomized names. On rare occasions, it generates a java.lang.reflect.InvocationTargetException.

The relevant code:

val now = new DateTime()

val timeIndex = s"${now.dayOfYear().get()}.${now.minuteOfDay().get()}"

val unicodeCharacter = Gen.choose(Char.MinValue, Char.MaxValue).filter(Character.isDefined)

def unicodeGenerator(generator: Gen[Char] = unicodeCharacter, minimum: Int = 5, maximum: Int = 20): Gen[String] = Gen.chooseNum(minimum, maximum).flatMap { n =>
    Gen.buildableOfN[String, Char](n, generator)
}

def nameGenerator(generator: Gen[String] = unicodeGenerator(), withIndex: Boolean = false) = generator.map(s => ((if (withIndex) timeIndex else "") + s.trim.capitalize) )

val randomName: String = nameGenerator().sample.get

The final line (above) is the line that generates:

[error] java.lang.reflect.InvocationTargetException
[error] caused by java.util.NoSuchElementException: None.get

This is pretty rare. I wrote a small unit test to reproduce it:

"use the random name generator" ! prop { (s: String) => { s.length >= 5 must beTrue } }.setGen(nameGenerator())

This test runs successfully several times in a row, but will fail roughly once every five times I run it, generating the following stack trace:

The underlying cause is due to calling Option.get, which you should never
do.

You are calling the Gen directly, which isn't normally how you'd use
ScalaCheck, you usually let the test framework create the test instances
for you.
