代码：

import com.sun.btrace.AnyType;
import com.sun.btrace.BTraceUtils;
import com.sun.btrace.annotations.BTrace;
import com.sun.btrace.annotations.Kind;
import com.sun.btrace.annotations.Location;
import com.sun.btrace.annotations.OnMethod;
import com.sun.btrace.annotations.ProbeClassName;
import com.sun.btrace.annotations.ProbeMethodName;

@BTrace
public class PrintArgSimple {

@OnMethod(
         clazz="com.imooc.monitor_tuning.chapter4.Ch4Controller",
         method="arg1",
         location=@Location(Kind.ENTRY)
)
public static void anyRead(@ProbeClassName String pcn, @ProbeMethodName String pmn, AnyType[] args) {
  BTraceUtils.printArray(args);
  BTraceUtils.println(pcn+","+pmn);
  BTraceUtils.println();
    }
}

错误信息：

** Compiling the BTrace script ...
*** Compiled
!!! Error occured

这是怎么回事呢，不兼容吗，应该怎么定位问题出在哪。
