Using jfreechart 1.0.19.
Using tomcat 7.0.37 and any version of java 1.7, the chart works.
Using tomcat 7.0.54+ and java version 1.7.0_25 or earlier, the chart works.
Using tomcat 7.0.54+ and any java version later than 1.7.0_25 results in an error. First time I go to the page which should have the chart I get:
All the following times the error is:java.lang.reflect.InvocationTargetException

Caused by: java.lang.NullPointerException

I have not tested with tomcats between 7.0.37 and 7.0.54. My environment is Ubuntu 10.04 LTS / Linux 2.6.32-37-generic.An error was propagated to the user level
javax.servlet.ServletException: java.lang.NoClassDefFoundError: Could not initialize class org.jfree.chart.JFreeChart

I do have the "java.awt.headless=true" configured in JAVA_OPTS - the tomcat process runs with the following attributes:
Does anyone have any idea what has changed in the combination of the later java and tomcat versions that results in the error for jfreecharts?/other/java/latest/jre/bin/java
