Memory leak aspose java

Hi,
Im having memory leakage problem. Aspose word is used only for translating document into pdf. This is my code:

  try ( ByteArrayOutputStream out = new ByteArrayOutputStream()) {
        // Call setLicense method to set license
        Document doc = new Document(new ByteArrayInputStream(decodedBody));
        doc.save(out, SaveFormat.PDF);
        //for testing
        return out.toByteArray();
    }

Then we use aspse pdf to stamp document and add headers and footers. Headers and footers are added as table and each value is in one cell of the table. Stamping is done with TextStamp class. I am moving document thorught different methods as aspose.pdf.Document object, and i am sure i close it at the end.

Here are the memory logs:

@velicko91

Would you please also share the complete code snippet related to Aspose.PDF that you are using along with a sample source document. We will test the scenario in our environment and address it accordingly. Plesae also confirm if you have tested the case with the latest available version of the API.

It is a bigger code, i can give you github access, just give me email.

@velicko91

You can give the Github access to the ID (@asadalikhan90) and confirm here when done. Also, please share the sample PDF document as well to test with the shared code. We will further proceed to assist you accordingly.

We’ve added you to github repo. I need to sent you rest json requests for the app. If you want to run it locally

@velicko91

We did not receive any GitHub notification for the repo. Would you please make sure to add the username as contributor and please share the link to the repo as well. You can also provide further information on how to run the code locally in order to replicate the issue at our side.

You are invited as it is seen on the image. image.png (44.5 KB)
This is link to repo: https://github.com/Simploud/SimploudPDF
You only need to change absolute path in application.properties.

Here are two different requests in attachmentrequest.zip (34.9 KB)

@velicko91

We were able to access the repository now and are looking into it. Meanwhile, could you please point out or share the name of .java file where the code related to Aspose.PDF is present?

Its called AsposePdfService. Also StampHeaderAspose is used for stumping headers.

@velicko91

We are afraid that we could not fine Aspose.PDF related code snippet in the files i.e. AsposeService.java and StampHeader.java. However, there was code related to iText library. Would you please rectify if we are not looking into right files. We could not find any other files in the shared application.

Hi ,
Sorry, i forgot to tell you what branch to look at. You should check asposePdf branch.

@velicko91

We have logged an investigation ticket as PDFJAVA-40033 in our issue tracking system for further analysis on this case. We will look into its details and keep you posted with the status of its correction. Please be patient and spare us some time.

We are sorry for the inconvenience.
