Bug 179133 Out of bounds chart exception when rendering a report using multiple threads
Reported: 2007-03-23 18:02:16 | Status: verified fixed

An out of bounds ChartException occurs when rendering reports using multiple threads. This was seen multiple times when running the performance test in org.eclipse.birt.test.performance project. To reproduce this exception, run the test after increasing the threads to 50 in case-10threads-pdf in org.eclipse.birt.test.performance/config.xml.
