FULL PRODUCT VERSION :
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows 2000 Professional 5.0.2195 SP4
A DESCRIPTION OF THE PROBLEM :
When printing a JEditorPane (see example), a spool file is created, that is 5 times larger than the spool file, that is created with Java 1.4
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Just print a JEditorPane with HTML input like in the example.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I would expect a spool file that is not noticable larger than that in Java 1.4
ACTUAL -
I get a spool file 5 times larger than that in Java 1.4
REPRODUCIBILITY :
This bug can be reproduced always.
