IBM JVM 1.6 SR14：java.lang.UnsatisfiedLinkError：fontmanager（未在com.ibm.oti.vm.bootstrap.library.path中找到）

Question

我們將AIX機器上的IBM Java從Java 1.6 SR 9升級到Java 1.6 SR14

Exception in thread "main" java.lang.UnsatisfiedLinkError: fontmanager (Not found in com.ibm.oti.vm.bootstrap.library.path)

     at Rtf.convert(Rtf.java:17) 
     at Rtf.main(Rtf.java:29) 

下面的代碼允許重現此問題：

import java.io.StringReader; 

import javax.swing.text.DefaultStyledDocument; 
import javax.swing.text.Document; 
import javax.swing.text.rtf.RTFEditorKit; 

public class Rtf { 

     public Rtf() { 
     } 

     static public String convert(String rtf) throws Exception { 
       DefaultStyledDocument styledDoc = new DefaultStyledDocument(); 
       RTFEditorKit rtfKit = new RTFEditorKit(); 
       StringReader reader = null; 
       reader = new StringReader(rtf); 
       rtfKit.read(reader, styledDoc, 0); 
       Document doc = styledDoc.getDefaultRootElement().getDocument(); 
       String txt = doc.getText(0, doc.getLength()); 
       return txt; 
     } 

     public static void main(String[] args) throws Exception { 
       System.getProperties().store(System.out, "Current System props"); 

       System.out.println("fontmanger LIB: "+ System.mapLibraryName("fontmanager")); 

       String rtf="{\\rtf1\\deff0{\\fonttbl{\\f0 Times New Roman;}{\\f1 Courier New;}}{\\colortbl\\red0\\green0\\blue0 ;\\red0\\green0\\blue255 ;}{\\*\\listoverridetable}{\\stylesheet {\\ql\\f1\\fs2

       String txt = Rtf.convert(rtf); 
     } 
} 

有沒有，如果沒有任何JVM參數運行RTF類的任何異常：

，現在我們已經把我們的應用程序的啓動過程中出現以下錯誤

java Rtf 

但如果與運行RTF類「-Dcom.sun.management.jmxremote」 JVM參數，那麼會出現例外「在線程異常‘主要’java.lang.UnsatisfiedLinkError中：fontmanager（COM中未找到.ibm.oti.vm.bootstrap.library.path）」：

java -Djava.awt.headless=true -Dcom.sun.management.jmxremote Rtf 

有誰知道如何解決這個問題？

解決方法是將目錄/ usr/java6_64/jre/lib/ppc64/xawt添加到當前的LIBPATH中。
