I see an occasional error running the 2.3.1 Birt Report Engine. It happens so infrequently, that I am wondering if it is a contention or race condition problem.<br />
<br />
The following errors occur when I am running multiple reports at the same time. Different report design files, located in different directories, called from command line genReport script (so they each have their own JVM), but calling the same BIRT 2.3.1 report engine.<br />
<br />
The two errors are basically:<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
java.util.zip.ZipException: error in opening zip file
</pre>
and <br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
java.lang.NoClassDefFoundError: org/w3c/tidy/Tidy
</pre>
<br />
I was thinking that maybe some race condition or contention causes the first error with the zip file as Birt is extracting the Tidy jar from it ... because I have noticed that a clean distribution of Birt does not have Tidy.jar but after running a report a copy is located in ...ReportEngineconfigurationorg.eclipse.osgibundles411.cplib.<br />
<br />
Anyone see this before or know what is going on?<br />
<br />
From the ReportEngine/configuration directory:<br />
