BUG: WTK2.2 io broken on Linux

Question

Hello,
I'm running an app that works perfectly (JavaVerified) in the Windows 2.2 WTK emulator, but it will not run under Linux because of this:
java.lang.ArrayIndexOutOfBoundsException:
at com.sun.kvem.cldc.i18n.j2me.GenericReader.read(+139)
at java.io.InputStreamReader.read(+56)
at j.a(+72)
at j.c(+5)
at j.b(+262)
at j.d(+23)
at s.a(+320)
at u.b(+655)
at u.run(+52)
Something's not right in Linux land.

Here's the test case I put together:
import javax.microedition.lcdui.CommandListener;
import javax.microedition.lcdui.Command;
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Displayable;
import javax.microedition.lcdui.Form;
import javax.microedition.midlet.MIDlet;
import java.io.ByteArrayInputStream;
import java.io.InputStreamReader;
public class HelloWorld extends MIDlet implements CommandListener
    Command quitCmd;
    Form    frm;
    Display disp;
    private static void testInputStream() {
     String str = "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789"
         + "0123456789";
     System.out.println("str: " + str);
     System.out.println("strlength: " + str.length());
     byte buf[] = str.getBytes();
     System.out.println("byte size: " + buf.length);
     ByteArrayInputStream bin = new ByteArrayInputStream(buf);
     InputStreamReader isr = new InputStreamReader(bin);
     char cBuf[] = new char[128];
     System.out.println("encoding: " +
         System.getProperty("microedition.encoding"));
     System.out.println("reading from buffer and printing.");
     try {
         int charsRead;
         while ((charsRead = isr.read(cBuf, 0, cBuf.length)) >= 0) {
          for (int i = 0; i < charsRead; i++) {
              System.out.print(cBuf);
     } catch (Exception ex) {
     ex.printStackTrace();
     System.out.println("\ndone reading");
public void startApp() {
     disp = Display.getDisplay(this);
     frm = new Form("HelloWorld");
     frm.append("Hello World");
     quitCmd = new Command("quit", Command.EXIT, 1);
     frm.addCommand(quitCmd);
     frm.setCommandListener(this);
     disp.setCurrent(frm);
     testInputStream();
public void pauseApp() {
public void destroyApp(boolean unconditional) {
     if (unconditional)
     notifyDestroyed();
public void commandAction(Command c, Displayable d)
     if (c == quitCmd)
     destroyApp(true);
I've run this on both Fedora Core3 & Fedora Core4 Linux distrubutions,
when I do - I get the following failure:
     [exec] Warning: Cannot convert string "-b&h-lucida-medium-r-normal-sans-*-140-*-*-p-*-iso8859-1" to type FontStruct

     [exec] 3 garbage collections (89956 bytes collected)This test case is what I put together after finding a failure of trying to run the kxml2 (www.kxml.org) XML parser under the emulator.
Any insights on why this is happening or if there is a work-around that can be applied would be appreciated.
Cheers,
