Bug ID: 65917
Summary: Image insertion fails
Product: POI
Version: 5.2.0-FINAL
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: XWPF
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Hey,
I am currently working on a project heavily utilizing Apache POI.
In one use case, we need to insert a table into an XWPF document, and in each
cell we insert a QR-Code.
I wrote a test for this verifying the behavior, which normally goes through
without problems. When running the full test suite (~75 tests), this test fails
though in about 50% of the time, with the following exception:
```
java.util.concurrent.CompletionException: java.lang.NullPointerException:
Cannot invoke
"org.apache.poi.openxml4j.opc.OPCPackage.getPart(org.apache.poi.openxml4j.opc.PackagePartName)"
because the return value of
"org.apache.poi.xwpf.usermodel.XWPFDocument.getPackage()" is null.
```
The insertion code is:
```
try (var in = Files.newInputStream(path, StandardOpenOption.READ)) {
return paragraph.createRun()
.addPicture(in, contentType, path.getFileName().toString(),
dim.width, dim.height);
} catch (InvalidFormatException | IOException e) {
logger.error("Could not insert image from given Path
%s.".formatted(path), e);
throw new IllegalArgumentException("Could not insert image form given
Path.", e);
}
```
I have other use cases where I use this method, also verified through testing,
where this exception does not get thrown.
Does somebody know what the problem here is/how to fix it?
Best regards
Anton
