Java 출력이 NetBeans와 콘솔간에 다릅니다.

Question

BOM (Byte Order Mark)을 포함하거나 포함하지 않고 파일을 구문 분석하고 있습니다.

CharBuffer buffer = allocateBuffer(); 
reader.read(buffer); 
buffer.flip(); 

나중에을 초기화하기 다음과 같은 방법

private void init() { 
    char first; 

    if (buffer.hasRemaining()) { 
     first = buffer.get(); 
     if (!isByteOrderMark(first)) { 
      buffer.rewind(); 
     } 
    } 
} 

아니라 BOM을 무시 호출, 그것은이 있고, 콘솔에

Parsing file "common\name_lists\AI.txt"... 
[FILL] file_size=6878, total_line=140 
[PARSE] parent=null, state=0 
[NEXT] line=1, next="AI" 
    cache=2 [=, {] 
[NEXT] line=1, next="=" 
    cache=1 [{] 
[NEXT] line=1, next="{" 
    cache=0 [] 

그러나 넷빈즈에서 잘 작동 밝혀졌다 다음 출력 :

Parsing file "common/name_lists/AI.txt"... 
    [FILL] file_size=6879, total_line=140 
    [PARSE] parent=null, state=0 
    [NEXT] line=1, next="�?" 
     cache=2 [AI, =] 
    [NEXT] line=1, next="AI" 
     cache=1 [=] 
    [NEXT] line=1, next="=" 
     cache=0 [] 
    [NEXT] line=2, next="{" 
     cache=2 [selectable, =]

     at com.stellaris.ScriptFile.main(ScriptFile.java:280) 

그때 내가 클래스 파일을 디 컴파일, 그것은 방법의

Compiled from "ScriptParser.java" 
public final class com.stellaris.ScriptParser { 
    public com.stellaris.ScriptParser(java.io.Reader); 
    private void init(); 
    private static boolean isByteOrderMark(char); 
    private static java.nio.CharBuffer allocateBuffer(); 
} 

바이트 코드 초기화 초기화 생성자 ScriptParser (리더 리더)에 호출

private void init(); 
    Code: 
     0: aload_0 
     1: getfield  #12     // Field buffer:Ljava/nio/CharBuffer; 
     4: invokevirtual #13     // Method java/nio/CharBuffer.hasRemaining:()Z 
     7: ifeq   33 
     10: aload_0 
     11: getfield  #12     // Field buffer:Ljava/nio/CharBuffer; 
     14: invokevirtual #14     // Method java/nio/CharBuffer.get:()C 
     17: istore_1 
     18: iload_1 
     19: invokestatic #15     // Method isByteOrderMark:(C)Z 
     22: ifne   33 
     25: aload_0 
     26: getfield  #12     // Field buffer:Ljava/nio/CharBuffer; 
     29: invokevirtual #16     // Method java/nio/CharBuffer.rewind:()Ljava/nio/Buffer; 
     32: pop 
     33: return 

방법

잘 보인다

public com.stellaris.ScriptParser(java.io.Reader); 
    Code: 
     0: aload_0 
     1: invokespecial #2     // Method java/lang/Object."<init>":()V 
     4: aload_0 
     5: new   #3     // class java/io/BufferedReader 
     8: dup 
     9: aload_1 
     10: invokespecial #4     // Method java/io/BufferedReader."<init>":(Ljava/io/Reader;)V 
     13: putfield  #5     // Field reader:Ljava/io/BufferedReader; 
     16: aload_0 
     17: new   #6     // class java/util/LinkedList 
     20: dup

     36: aload_0 
     37: invokespecial #11     // Method init:()V 
     40: return

는을 초기화하기 방법 는

제 4 자 (16 진수, 콘솔)

다음과 같은 클래스를 사용하여 이러한 충돌을 피하고 있습니다. 왜 그런지는 아직 모릅니다.
