Rendering report with cross tab

maxime

Hi,

I am writing my own birtviewer using the api. The environment of my application is jdk 1.5, tomcat 5.5, birt runtime 2.3.0

I've got a problem when i render a report with cross tab. For all my other reports everything is ok. However in this case when I execute the runTask.run(), an exception always happens :

2008-09-19 16:36:32,156 http-8080-Processor24 INFO [plugins.advancedreports.web
actions.RunAndRenderReportAction] No error during the run task execution.

This is the first case. The whorst is when i try to render a report composed with a crosstab and another component like chart or other crosstab...
Then I can render my report only few times (5~10) to a server crash.

After thread dump analyse I can see :
