In Turkish locale, fields starting with the character "i" are lost

Not repeated in other locales.
In Turkish locale, the @JvmField annotation can be used as a workaround.

Kotlin JUnit example:

data class Pizza(
    //@JvmField
    val ingredients: String,
    //@JvmField
    val sauces: String,
)

@Test
fun testMustacheInTurkishLocale() {
    Locale.setDefault(Locale("tr", "TR"))
    val factory = DefaultMustacheFactory()
    val ingredients = "cheese, pepperoni"
    val sauces = "tomato"
    val template = "pizza: ingredients: {{ingredients}}; sauces: {{sauces}}."
    val mustache = ByteArrayInputStream(template.toByteArray()).use { input ->
        factory.compile(input.bufferedReader(), "template_name")
    }
    val pizza = Pizza(ingredients, sauces)
    val actual = ByteArrayOutputStream().use { out ->
        PrintWriter(out).use { writer ->
            mustache.execute(writer, pizza)
        }
        String(out.toByteArray(), Charsets.UTF_8)
    }
    println(actual)
    val expected = "pizza: ingredients: $ingredients; sauces: $sauces."
    assertEquals(expected, actual)
}

Start by running the Kotlin JUnit example with Locale.setDefault(Locale("tr", "TR")) and trace the behavior from DefaultMustacheFactory. Done means the ingredients and sauces fields render correctly in the Turkish locale without requiring @JvmField, while the existing behavior in other locales remains intact.
