------------------------------------
Can you try this patch, and change your PrintService code to call
print(Graphics) instead of paint(Graphics)

> Printing crashes with Out Of Memory exception

> Key: PIVOT-815
> URL: https://issues.apache.org/jira/browse/PIVOT-815
> Project: Pivot
> Issue Type: Bug
> Components: wtk, wtk-terra
> Affects Versions: 2.0
> Environment: Windows 7 x64, Java 1.6.0_29
> Reporter: Drazen Dotlic
> Assignee: Sandro Martini
> Labels: crash, outofmemory, printing
> Fix For: 2.0.1
>
>
> Printing using Java's Printable interface... We have a single Pivot Window
> (it's an applet) and the layout isn't really complicated. Implementing print
> method of the Printable interface in our case boils down to drawing into the
> provided Graphics.
> This has worked perfectly until recently (not sure which version broke
> things, but we're talking last few weeks). Now when we print we get an "Out
> of Memory" exception. Call stack does not show any obvious anomalies like
> infinite loops and such, here it is:

> If you need more info, do not hesitate to ask. I would have provided a test
> case, but it's not easy to extract code from a commercial product. Besides, I
> suspect this is some kind of obvious accidental mistake which should be easy
