Summary: HeadlessException with headless=true and JRE 1.6.0_20-b02

Initial Comment:
Since yesterday I get for my JSF application (running on tomcat) a java.awt.HeadlessException while calling ChartFactory.createXYStepChart(...). java.awt.headless is set to true.

Here my Code:

System.out.println("_________________java.awt.headless is " + System.getProperty("java.awt.headless"));
    // create the chart:
    JFreeChart chart = ChartFactory.createXYStepChart(
        null, null, "%", dataset, PlotOrientation.VERTICAL, true, false, false);

And here a part of the exception:

_________________java.awt.headless is true
...

Interesting are the "com.birosoft...." lines in the stacktrace. I have never heared something about birosoft. Then I have check in which jar the com.birosoft classes are stored and have find out that the jar is .../jre/lib/ext/liquidInf.jar of the JRE 1.6.0_20-b02. It seems that the JRE 1.6.0_20-b02 was installed some days ago (may be a automatic update ...). The JRE 1.6.0_17 don't have this liquidInf.jar. I have switched back to the JRE 1.6.0_17 and all running fine without any Exceptions ... :-)

I run my JSF-application in tomcat on a openSuse 11.2 (this is my development machine; tomcat will be started over the eclipse IDE).

See also http://www.jfree.org/phpBB2/viewtopic.php?f=3&t=30073

Could you check if this is a bug in JFree or a bug of JRE 1.6.0_20 or is something other wrong with my installation?

Do you need more information? Please contact me.

Thanks,
Steffen

Even if you don't fix this, showing a workaround would be great!

Message:
I have the same problem. When I'm SSH-ing remotely to my application that
uses JFreeChart and using it to generate a chart to a PNG file, I get:

	at java.awt.GraphicsEnvironment.createGE(GraphicsEnvironment.java:118)

	at org.jfree.chart.JFreeChart.<clinit>(JFreeChart.java:258)
	at org.jfree.chart.ChartFactory.createXYLineChart(ChartFactory.java:1748)

Inspecting the JFreeChart code, specifically: 

http://jfreechart.cvs.sourceforge.net/viewvc/jfreechart/jfreechart/source/org/jfree/chart/JFreeChart.java?revision=1.34.2.21&view=markup

it appears that there is a static field:

    public static final Paint DEFAULT_BACKGROUND_PAINT  =
UIManager.getColor("Panel.background");

Apparently, getting the color from the UI manager cannot be done remotely
without a UI session (this also happens to me if the display goes into
screen saving mode).
I am running this on Mac OS X Lion, Oracle JVM 1.7, update 9. I don't think
this is a UI manager problem.

This is the only place in that file that the UIManager is used. Perhaps it
would make sense to fix this somehow or suggest a workaround - apparently,
it makes it impossible to use JFreeChart other than from a UI.

Message:
This is a bug in your Look-And-Feel. Someone installed that Look-And-Feel
in your JDK's installation directory and apparently your application
manually activates it (as a custom look-and-feel is not used unless you
explicitly request it.)  This seems to be a clear bug in their
implementation, as a call to UIManager.getDefaults() must never result in a
error.
