Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)
FULL OPERATING SYSTEM VERSION : Windows NT Version 4.0,
service pack 6a, german
EXTRA RELEVANT SYSTEM CONFIGURATION :
Acrobat PDF Writer: customer Portable Document Format Driver 4.05
Seiko Smart Label Printer 240, Driver CD is Labeled "Version
4.56"
A DESCRIPTION OF THE PROBLEM :
Calling draw on a TextLayout customer from a LineBreakMeasurer
produces lower quality rendering under some circumstances.
The quality is as expected when draw is called on a directly
instatiated TextLayout or when calling Graphcis.drawString.
The poor quality is only visible when printing to
a) Seiko smart label printer 240
b) customer Acrobat PDF writer
and the output is ok for a Laserjet 3150 and the screen.
For the PDF produced by the Acrobat PDF writer the
difference is visible only on the screen, the file can be
printed perfectly on a Laserjet 3150.
When printing small fonts on the label printer (e.g. size 7)
the quality of the output is unacceptable low.
Here is a uuencoded PDF produced from the attached example code:

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. run the attached example code
2. print to an Acrobat pdf writer
3. view the pdf on screen
notice the visual difference betweem the two lines
which are produced from different TextLayouts
Another effect:
1. remove the commented line
//
System.out.println("d="+layoutd);
2. compile, run
3. print to customer acrobat writer
4. view the PDF: both lines have the same bad quality!
EXPECTED VERSUS ACTUAL BEHAVIOR :
Same viusal quality for both TextLayouts and Graphcis.draw.
REPRODUCIBILITY :
This bug can be reproduced always.
