[Bug awt/27711] New: bootchart trigger java.lang.InternalError in GdkGraphics2D.cairoDrawGlyphVector

[pere at hungry dot com]

When trying to generate PNG output from bootchart using the CVS
version of Classpath and jamvm, I get an assert error.  The source for
bootchart is available from
<IURL:http://www.bootchart.org/download.html>.  This is how I run it
on Debian/unstable.

% jamvm -Djava.awt.headless=true -classpath
/usr/share/bootchart-view/bootchart.jar:/usr/share/java/commons-cli.jar
org.bootchart.Main -f png /usr/share/doc/bootchart-view/examples/bootchart.tgz
