this is some problem with the numbers of components being different. Try
pdfbox-app instead.

Betreff: Re: Possible memory leak when extracting text?

An: users@pdfbox.apache.org
I have been trying to add the 2.0.16-SNAPSHOT version as a dependency to my
application, but I keep having issues. I added this to my pom file:
<repositories>
<repository>
<id>repository.apache.org.snapshots</id>
<http://repository.apache.org.snapshots</id>> ;
<name>Apache snapshots repo</name>
<url>https://repository.apache.org/content/groups/snapshots/</url>
<https://repository.apache.org/content/groups/snapshots/</url>> ;
<snapshots>
<enabled>true</enabled>
</snapshots>
<releases>
<enabled>false</enabled>
</releases>
</repository>
</repositories>
And then I added this under dependencies:
<dependency>
<groupId>org.apache.pdfbox</groupId>
<artifactId>pdfbox</artifactId>
<version>2.0.16-SNAPSHOT</version>
</dependency>
When I run “mvn compile” I get this error:
[ERROR] Failed to execute goal on project pdftextextractor: Could not

I am probably missing something obvious, but I haven’t been working with
Java for that long, so I have no clue what to do (my googling skills did
not prevail).
Do you have any tips?
Thanks a lot in advance!
Best regards,
Søren

The reason I mentioned 2.0.16 is because of this bug:
https://issues.apache.org/jira/browse/PDFBOX-4489
<https://issues.apache.org/jira/browse/PDFBOX-4489>
that one happened with a corrupt file. Yours isn't, but it might be if
it gets corrupted in transfer or in filtering.
2.0.16 snapshot is here:
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox-app/2.0.16-SNAPSHOT

Ok, that is very interesting. Thanks a lot for looking into this!
I am a bit baffled as to why we experience the memory leak then, but I
guess I will have to dig more into it.
Best regards,

I have done some more testing, and I found that when I run on
Windows there are no problems, but when I run on Linux I get the memory
leak. Tilman, would you be able to run the same test on a Linux box? - or
maybe using a Linux Docker container, like I showed originally?
I've extracted the text on linux (fedora 30, openjdk 1.8.0_212)
without any
problems using
java -Xmx9m -jar pdfbox-app-2.0.15.jar ExtractText
where -Xmx9m is the smallest working value

We would prefer to run our app on Linux, but this looks like a
blocker for that unfortunately :(

We have an application that can index the contents of PDF
files, so that we
can use that for a search algorithm. We use the Apache PDFBox
library for
extracting text from a PDF, like this (where inputStream is a
ByteArrayInputStream containing the contents of the PDF
file):
PDFTextStripper pdfStripper = new PDFTextStripper();
pdDoc = PDDocument.load(inputStream,
MemoryUsageSetting.setupTempFileOnly
<http://MemoryUsageSetting.setupTempFileOnly> ());
String parsedText = pdfStripper.getText(pdDoc
<http://pdfStripper.getText(pdDoc> );
You can pass the byte[] directly to load(). Also make sure that
the
bytes are not altered in any way, e.g. through a incorrectly
configured
web downloading, or an incorrectly configured resource loading
("filtering" option must be false).
Also retry with 2.0.16 snapshot.
