Bug 137817 NPE while generating PDF report
Got this excecption when generating a big PDF report. The PDF report fails and a browser error page is displayed: WARNING: D:\workspaces\runtime-workspace\.metadata\.plugins\com.ibm.xtools.analysis.reporting\reports\codereview_severity_summary\codereview_severity_summary.pdf (The system cannot find the path specified) java.io.FileNotFoundException: D:\workspaces\runtime-workspace\.metadata\.plugins\com.ibm.xtools.analysis.reporting\reports\codereview_severity_summary\codereview_severity_summary.pdf (The system cannot find the path specified) at java.io.FileOutputStream.open(Native Method) at java.io.FileOutputStream.<init>(FileOutputStream.java:201) at java.io.FileOutputStream.<init>(FileOutputStream.java:153) at org.eclipse.birt.report.engine.emitter.pdf.PDFEmitter.initialize(PDFEmitter.java:186) at org.eclipse.birt.report.engine.layout.impl.ReportLayoutEngine.initialize(ReportLayoutEngine.java:381) at org.eclipse.birt.report.engine.presentation.WrappedEmitter.initialize(WrappedEmitter.java:44) at org.eclipse.birt.report.engine.presentation.LocalizedEmitter.initialize(LocalizedEmitter.java:129) at org.eclipse.birt.report.engine.api.impl.RunAndRenderTask.createContentEmitter(RunAndRenderTask.java:145) at org.eclipse.birt.report.engine.api.impl.RunAndRenderTask.run(RunAndRenderTask.java:174) at com.ibm.xtools.analysis.reporting.internal.editor.ReportEditor$1.runInWorkspace(ReportEditor.java:167) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:38) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:58)
