Build Identifier: Version: Helios Service Release 2, Build: 20110218-0911 Hi. This happens once every couple of hundreds of rendered PDF.. I'm developing a multi-threaded java 6 solution on SuSE 11. Each thread works its way through the data, builds a report based on its own template and somewhere along the way saves that template with a couple of changes. The code goes like this: ... ReportDesignHandle reportDesign = null; ... reportDesign = session.openDesign(thisDesignFile); ... reportDesign.saveAs(thisDesignFile); ... For purpose's sake I might as well add that after populating two embedded images, the final template is rendered to PDF. I've been debugging for the last couple of weeks and have been able to cut way through all I've stubled upon - until now: In the midst of tens of data and rendered PDF, one thread, with one specific but not unusual set of data, throws an exception when trying to save the template. Most puzzling is the message associated to the exception: 22868. The cause is null. The template is saved, but ill-formed since it's not complete: <?xml version="1.0" encoding="UTF-8"?> <report xmlns="http://www.eclipse.org/birt/2005/design" version="3.2.22" id="1"> <property>...</property> ...other normal stuff... <styles>...</styles> <page-setup>...</page-setup> <body>...</body> <list-property name="images"> <structure> <property name="name">myImage.jpg</property> And that's where it ends; there's nothing wrong with this image, as tens of other reports render it perfectly int their PDF. It is embedd3ed, although, due to rendering problems, I have to load it dynamically again into the template - if not, 5-8% of the times it will be rendered as "Current item is not available". What is Exception 22868? Stack Print is as follows: java.lang.ArrayIndexOutOfBoundsException: 22868 at org.apache.commons.codec.binary.Base64.encode(Base64.java:500) at org.apache.commons.codec.binary.Base64.encode(Base64.java:936) at org.eclipse.birt.report.model.writer.ModuleWriterImpl.writeEmbeddedImages(ModuleWriterImpl.java:1528) at org.eclipse.birt.report.model.writer.DesignWriterImpl.writeImages(DesignWriterImpl.java:217) at org.eclipse.birt.report.model.writer.DesignWriterImpl.visitReportDesign(DesignWriterImpl.java:86) at org.eclipse.birt.report.model.elements.ReportDesign.apply(ReportDesign.java:65) at org.eclipse.birt.report.model.writer.ModuleWriterImpl.writeFile(ModuleWriterImpl.java:314) at org.eclipse.birt.report.model.writer.ModuleWriterImpl.write(ModuleWriterImpl.java:282) at org.eclipse.birt.report.model.api.ModuleHandleImpl.save(ModuleHandleImpl.java:1440) at org.eclipse.birt.report.model.api.ModuleHandleImpl.saveAs(ModuleHandleImpl.java:1460) at pt.banif.reporting.engine.BIRTDesignRenderer.call(BIRTDesignRenderer.java:566) at pt.banif.reporting.generator.BIRTReportGenerator$DesignRendererConsumer.call(BIRTReportGenerator.java:1284) at pt.banif.reporting.generator.BIRTReportGenerator$DesignRendererConsumer.call(BIRTReportGenerator.java:1) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Is this an org.apache.commons.codec.binary.Base64.encode problem with the image?

Regards, Susana Reproducible: Sometimes Steps to Reproduce: 1.A report template with and embedded logo 2.Reloading the logo before rendering to pdf 3.Lots of threads doing the same thing, each using it's own copy of both template and logo.
Solved. It was due my mistake all the time; the error message simply didn't point in any direction. The solution has one main-thread which spawns N children. It uses a queue to place each reposrts info and the children are the renderers. My mistake was to have the main-thread create everything down to the run-time session and pass each child a reference to that session. Since no one ever closed anything regarding the session, it grew tremendously. Only when I was checking out memory consumption did I stumble upon this. The fix was to pass a reference to the run-time engine and have each child open/close it's own session. Since then we have processed thousands of reports and this issue has never occurred again.
