Bug 314645 XML Datasource is not Thread-Safe when passing data as InputStream
Build Identifier: Eclipse Build id: 20090920-1017 / BIRT Runtime 2.5.1 + 2.5.2 When passing XML-data to the IRunTask in a multi-threaded application, some of the resulting .rptdocument files will be corrupted. The error only occures when passing an InputStream using the setAppContext method: ctxMap.put("org.eclipse.birt.report.data.oda.xml.inputStream", new FileInputStream("data.xml")); ctxMap.put("org.eclipse.birt.report.data.oda.xml.closeInputStream", new Boolean(true)); task.setAppContext(ctxMap); This warning will be written to the log: "WARNUNG: Exceptions occur during xml parsing" (see attachments for stackstrace) Reproducible: Sometimes Steps to Reproduce: 1. Run the sample application in the attachments (use the -Xmx1024m VM-Argument to avoid our of memory errors 2. Wait till the log shows the this warning: WARNUNG: Exceptions occur during xml parsing 3. Kill the sample application process 4. Analyze the generated rptdocument files (sort by ascending file size to find corrupted files)
