我们将 AIX 机器上的 IBM Java 从 Java 1.6 SR 9 升级到 Java 1.6 SR14,现在我们在应用程序启动期间出现以下错误:

以下代码允许重现此问题:
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);
}
}
如果在没有任何 jvm 参数的情况下运行 Rtf 类,则没有任何例外:
java Rtf
但是,如果使用“-Dcom.sun.management.jmxremote” jvm 参数运行 Rtf 类,则会出现异常“线程“main”中的异常 java.lang.UnsatisfiedLinkError: fontmanager (Not found in com.ibm.oti.vm. bootstrap.library.path)":
java -Djava.awt.headless=true -Dcom.sun.management.jmxremote Rtf
有谁知道如何解决这个问题?
