method signature seems wrong

[zhangjunhd]

hi,
I want to reflect a high-order function of scala,so i use classUtil to track it, but I found the print sigature of the method is wrong(just print as method name):

import org.clapper.classutil.ClassFinder
import org.clapper.classutil.ClassUtil

import java.io.File

object Main extends App {

val classpath = List(
    new File("target/scala-2.10/classes/com/alibaba/fodps/classUtil/"))
val finder = ClassFinder(classpath)
//val classes = finder.getClasses // classes is an Iterator[ClassInfo]

println("interface ...")
val ifaces = finder.getClasses.filter(_.isInterface)
ifaces.foreach(println(_))

println("concrete ...")
val crete = finder.getClasses.filter(_.isConcrete)
for (cls <- crete){
    println(cls.name)
    if (cls.name == "com.alibaba.fodps.classUtil.Foo$$anonfun$run$1"){
        printf("bingo, methods:%s\n",cls.methods)
        for (m <- cls.methods){
            if (m.name == "apply")
                printf("desc=%s,sig=%s\n", m.descriptor, m.signature)
        }
    }
}

}

use sbt and print:
