Loading sequence physical fonts

Question

Hi guys,
I have one concern=> Please can somebody explain the loading sequence of physical fonts.
Why do I ask?
I wrote some JUnit tests where I compare the current rendering output with an reference image.
Some tests draw a text with the Lucida Sans font-family and their different styling options. (PLAIN, BOLD, ITALIC, BOLD&ITALIC)
The JUnit tests will be executed on different machines (Windows 7 x64 - SP1 - GERMAN, JDK 7u45 x64) and on the build server (Windows Server 2008 R2 x64 - ENGLISH, JDK7u45 x64) and my problem is now that the results between the Windows 7 machines and the server are not equal.
I've found already the reason for this=> the loading sequence of the physical fonts is different.
used physical fonts on the Windows 7 machine (GERMAN):
Lucida Sans [PLAIN] - C:\Program Files\Java\jre7\lib\fonts\LucidaSansRegular.ttf
Lucida Sans [BOLD] - C:\Program Files\Java\jre7\lib\fonts\LucidaSansDemiBold.ttf
Lucida Sans [ITALIC] - C:\Program Files\Java\jre7\lib\fonts\LucidaSansRegular.ttf
Lucida Sans [BOLD_ITALIC] - C:\Program Files\Java\jre7\lib\fonts\LucidaSansDemiBold.tt
used physical fonts on the Windows 2008 server (ENGLISH):
Lucida Sans [PLAIN] - C:\Program Files\Java\jre7\lib\fonts\LucidaSansRegular.ttf
Lucida Sans [BOLD] - C:\Program Files\Java\jre7\lib\fonts\LucidaSansDemiBold.ttf
Lucida Sans [ITALIC] - C:\Windows\Fonts\lsansi.ttf
Lucida Sans [BOLD_ITALIC] - C:\Windows\Fonts\lsansdi.ttf
Now my questions:
1. Why loads the Windows Server 2008 the windows native font if the style is ITALIC?
2. Am I right that the following behaviour is the typical loading sequence?
     -> physical fonts in JAVA_HOME\lib\font
     -> physical fonts in the OS directory
3. Is there a possibilty/ VM property which allows me to change the loading sequence ? So that the VM preferes the fonts in the OS directory instead of the physical font?
Thank you for your help!!
Regards,
Steve

Sample Code:
public class TestPhysicalFonts
  private enum Style
  PLAIN,
  BOLD,
  ITALIC,
  BOLD_ITALIC;
  public static void main(String[] args) throws IOException, NoSuchFieldException, SecurityException, IllegalArgumentException,
  IllegalAccessException, NoSuchMethodException, InvocationTargetException
  Method getFont2DMethod = Font.class.getDeclaredMethod("getFont2D");
  getFont2DMethod.setAccessible(true);
  Field platName = PhysicalFont.class.getDeclaredField("platName");
  platName.setAccessible(true);
  // String[] fontNamesToTest = GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames();
  String[] fontNamesToTest = new String[] { "Lucida Sans" };
  try (OutputStream outputStream = Files.newOutputStream(Paths.get("C:\\physicalFonts.txt"));
  PrintStream printStream = new PrintStream(outputStream))
  for (String fontFamily : fontNamesToTest)
  for (Style style : Style.values())
  Font font = new Font(fontFamily, style.ordinal(), 10);
  Font2D font2d = (Font2D) getFont2DMethod.invoke(font);
  if (font2d instanceof PhysicalFont)
  PhysicalFont physicalFont = (PhysicalFont) font2d;
  printStream.println(String.format("%s [%s] - %s", font.getName(), style.name(), platName.get(physicalFont)));
UPDATE:
1. If I doesn't execute the sample code from eclipse, than I get the same result as on the server... that means ....
Lucida Sans [PLAIN] - C:\Program Files\Java\jre7\lib\fonts\LucidaSansRegular.ttf
Lucida Sans [BOLD] - C:\Program Files\Java\jre7\lib\fonts\LucidaSansDemiBold.ttf
Lucida Sans [ITALIC] - C:\Windows\Fonts\lsansi.ttf
Lucida Sans [BOLD_ITALIC] - C:\Windows\Fonts\lsansdi.ttf
2. If I set the default Locale to ENGLISH, than I get the same result as in eclipse... that means ...
Lucida Sans [PLAIN] - C:\Program Files\Java\jre7\lib\fonts\LucidaSansRegular.ttf
Lucida Sans [BOLD] - C:\Program Files\Java\jre7\lib\fonts\LucidaSansDemiBold.ttf
Lucida Sans [ITALIC] - C:\Program Files\Java\jre7\lib\fonts\LucidaSansRegular.ttf
Lucida Sans [BOLD_ITALIC] - C:\Program Files\Java\jre7\lib\fonts\LucidaSansDemiBold.tt
