Description Hugo Corbucci CLA 2011-05-02 20:46:44 EDT 
Build Identifier: 20110218-0911

On Windows (XP, Vista and 7), when trying to render a TextLayout with strikeout style and a selection on this style, the GC with a transform crashes the JVM with the following error:

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x09d01f00, pid=3116, tid=2340
#
# JRE version: 6.0_25-b06
# Java VM: Java HotSpot(TM) Client VM (20.0-b11 mixed mode, sharing windows-x86 )
# Problematic frame:
# C  0x09d01f00

Apparently any transform will cause the problem, even if an empty transform. It doesn't happen to bold, italic, underline or any other style.


Reproducible: Always

Steps to Reproduce:
1. Create a TextLayout with some text and a strike out style.
2. On paint, set a transform on the GC.
3. Draw the text layout with selection containing the range which is struck out.

Worked perfectly for us. Thank you!
Not changing the status since we're not familiar with the process but it looks RESOLVED to us.
