With kotlin and API 21 the above code becomes

@Throws(IOException::class)
private fun getStartTime( pid:Int ) : Long { 
    val reader = BufferedReader(FileReader ("/proc/$pid/stat"));
    val stats = try {
        reader.readLine();
    } finally {
        reader.close();
    }
    val fieldStartTime = 20;
    val msInSec = 1000;
    try {
        val fields = stats.substring (stats.lastIndexOf(") ")).split(" ");
        val t = fields[fieldStartTime].toLong();
        val tck = Os.sysconf(OsConstants._SC_CLK_TCK);
        return (t * msInSec) / tck;
    } catch (e: NumberFormatException) {
        throw IOException (e);
    } catch (e: IndexOutOfBoundsException ) {
        throw IOException (e);
    }
}
