IBMJVM1.6 SR14: java.lang.UnsatisfiedLinkError: fontmanager (未在com.ibm.oti.vm.bootstrap.library.path中找到)

Question

我们将AIX机器上的IBM从Java1.6SR 9升级为Java1.6 SR14，现在我们在应用程序启动时出现了以下错误：

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
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

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

如果在没有jvm参数的情况下运行Rtf类，则没有任何异常：

java Rtf

但是，如果要使用"-Dcom.sun.management.jmxremote" jvm参数运行Rtf类，那么将出现异常“com.ibm.oti.vm.bootstrap.library.path)"：中的异常”：：fontmanager (不在com.ibm.oti.vm.bootstrap.library.path)“：中找到)。

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

有人知道如何解决这个问题吗？

解决方法是将/usr/java6 6_64/jre/lib/ppc64 64/xawt目录添加到当前的LIBPATH中。
