java - IBM JVM 1.6 SR14 : java. lang.UnsatisfiedLinkError : fontmanager (Not found in com. ibm.oti.vm.bootstrap.library.path)

Question

我们将 AIX 计算机上的 IBM Java 从 Java 1.6 SR 9 升级到 Java 1.6 SR14，现在在启动应用程序期间出现以下错误:

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)

以下代码可以重现此问题:

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
0\\cf0 Normal;}{\\*\\cs1\\f1\\fs20\\cf0 Default Paragraph Font;}{\\*\\cs2\\sbasedon1\\f1\\fs20\\cf0 Line Number;}{\\*\\cs3\\ul\\f1\\fs20\\cf1 Hyperlink;}}\\sectd\\pard\\plain\\ql{\\f1\\fs20\\cf0 draw 2 extra
 6ml lav. label with chart labels\"}\\f1\\fs20\\par\\pard\\plain\\ql{\\f1\\fs20\\cf0 ?When to Transfuse: When Avl}\\f1\\fs20\\par}";
                String txt = Rtf.convert(rtf);
        }
}

如果在没有任何 jvm 参数的情况下运行 Rtf 类，则没有任何异常(exception):

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 "Thread "main"java.lang.UnsatisfiedLinkError: 异常: fontmanager(在 com.ibm.oti.vm.bootstrap.library.path 中找不到)”:

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

有人知道如何解决这个问题吗？

Answer 1

解决方法是将目录/usr/java6_64/jre/lib/ppc64/xawt 添加到当前 LIBPATH。
