FULL PRODUCT VERSION :
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Windows XP Professional

A DESCRIPTION OF THE PROBLEM :
We have an application that overrides Printable.print method in which we does several
Graphics2D.drawString() in loop.
The problem is that the amount of time to be executed and the object created increases with memory usage
when drawString method is called compared to Java1.4.2.

This leads to Garbage Collection to occur often. In a result, there is a noticeable performance degradation in our application.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the following test case

ACTUAL -
Java1.4 - 14813ms
Java6.0 - 57797ms


REPRODUCIBILITY :
This bug can be reproduced always.
