Dear Ms/Mr. We’ve got the following problem with the FlexiCapture Engine and we need some help in order to solve it. Every time we run our Java code in order to process a .pdf file we do this:

IEngineLoader loader = null;
IEngine engine = null;
try {
loader = Engine.CreateEngineOutprocLoader();
engine = loader.Load(PropertiesUtil.getProperty("flexicapture.key"), "");
try {
IFlexiCaptureProcessor processor = engine.CreateFlexiCaptureProcessor();
String pdfFilePath = createFile(idCliente, idProveedor, pdfFileName, pdfFileData);
String definitionFilePath = createFile(idCliente, idProveedor, plantilla.getNombreFicheroPlantilla(), plantilla.getFicheroPlantilla()); I
DocumentDefinition documentDefinition = engine.CreateDocumentDefinitionFromAFL(definitionFilePath, "Spanish"); processor.AddDocumentDefinition(documentDefinition);
if (pdfFilePath != null)
{ processor.AddImageFile(pdfFilePath); }
IDocument document = null;
while ((document = processor.RecognizeNextDocument()) != null)
{ //HERE WE READ AL THE DATA AND DO ALL THE STUFF }
if (documentDefinition != null)
{ documentDefinition.Release(); documentDefinition = null; }
// Liberar recursos File pdfFile = new File(pdfFilePath);
Files.delete(pdfFile.toPath());
File definitionFile = new File(definitionFilePath);
Files.delete(definitionFile.toPath()); }
finally {
if (engine != null)
{ engine.Release(); engine = null; }
if (loader != null)
{ loader.Unload();
loader.Release();
loader = null; }
// Engine.Unload(); }

As you can see we’re making sure of releasing all the resources and unloading the engine but we get a new process with every execution as you can see here: They remain alive in the memory with a size of around 10MB. (see attached capture)

We tried to declare the main classes of the engine as static also:
static IEngineLoader loader = null;
static IEngine engine = null;
static IFlexiCaptureProcessor processor = null;
and only instantiate them once, and we get the same result.

How can we get rid of these processes?

We really appreciate any help you can provide. Best regards.
