运行批量请求时Jasper报告错误

当前，在我的项目中，我们尝试使用jasper导出pdf文件

代码看起来像这样

{
    ...
    //report Folder and path define here
    String reportFolder = env.getProperty(APIConstant.PATH_REPORT_TEMPLATE);
    String reportPath = reportFolder + prdcode + APIConstant.FILE_TYPE_JASPER;
    ...
    printFileName = JasperFillManager.fillReportToFile(reportPath, params);
    if (printFileName != null) {
        JasperExportManager.exportReportToPdfFile(printFileName, illufilename); //Exception come from this line
    }
    ...
} catch (Exception e) {
    ...
}

当我尝试使用JMeter进行性能测试时，问题就来了，一次设置了50个用户调用的线程。例外是

net.sf.jasperreports.engine.JRException: Error loading object from file: D:\workspace\document\Report\ULP1.jrprint.
java.io.EOFException ....

有一点是printFileName在所有50通话中都相同吗？

更新完整的错误日志：

从我的角度来看，您不应调用JasperFillManager.fillReportToFile，而应调用JasperFillManager.fillReport，而应让jasper处理文件本身。

//printFileName = JasperFillManager.fillReportToFile(reportPath, params);
jasperPrint = JasperFillManager.fillReport(reportPath, params);
if (jasperPrint != null) {
    //JasperExportManager.exportReportToPdfFile(printFileName, illufilename);
     JasperExportManager.exportReportToPdfFile(jasperPrint, illufilename);
}
