We are using Java under Windows to call the FineReader Engine 11. Sometimes, when executing the code below, an EXCEPTION_ACCESS_VIOLATION occurs in Image.Helper.Pdf.dll and the Java Virtual Machine is terminated.

Here's the relevant code:

public void train(IEngine engine, String targetClass, byte[] pdfContent, int page) { IFRDocument rawDocument = engine.CreateFRDocument(); IPrepareImageMode pim = ... rawDocument.AddImageFileFromMemory(pdfContent,null, pim, null, "some.pdf"); ... }

The error occurs when calling rawDocument.AddImageFileFromMemory. It does not seem to be related to a single, possibly broken PDF file. For different PDFs calling AddImageFileFromMemory works most of the time, while occasionally we get the EXCEPTION_ACCESS_VIOLATION error.

Any hint on how to fix or circumvent this error would be highly appreciated

Kind Regards


Here's the error as reported by the JVM

A fatal error has been detected by the Java Runtime Environment:

I would like to add that the OpenImageFileFromMemory does not work if the Engine object is created using the OutprocLoader object. You could find this remark in the "OpenImageFileFromMemory Method of the Engine Object" article of the Developer's Help (section Remarks).

I got the same error today when opening a PDF file with a call to engine.OpenImageFileFromMemory:

For info, I found the cause of the exception: I had multiple threads trying to process documents at the same time. The engine is not thread-safe by default.

I had to create the engine by using:

engineLoader = Engine.CreateEngineOutprocLoader();
engine = engineLoader.GetEngineObject(serialNumber);

Indeed, I needed to use FRDocument.AddImageFileFromStream instead to make it work with OutprocLoader.
