javax.xml.bind.JAXBException: namespacePrefixMapper is null

[klausT]

Hi Jason,

After upgrading to the new version 8.1.1 we get this kind of error:

Code: Select all

java.lang.RuntimeException: javax.xml.bind.JAXBException: namespacePrefixMapper is null
   at org.docx4j.XmlUtils.marshaltoW3CDomDocument(XmlUtils.java:983) ~[docx4j-core-8.1.1.jar:?]
   at org.docx4j.XmlUtils.marshaltoW3CDomDocument(XmlUtils.java:941) ~[docx4j-core-8.1.1.jar:?]
   at org.docx4j.model.datastorage.OpenDoPEIntegrity.process(OpenDoPEIntegrity.java:140) ~[docx4j-core-8.1.1.jar:?]

   at com.arianim.swingworker.docx.DocxGenerator$1$1.run(DocxGenerator.java:257) [bin/:?]


The full log (with Docx4j log level "WARN" can be found in the attachment.

Interestingly, this only happens when I generate documents in parallel (multi-threaded).
When generating a single document everything works fine.

We are using docx4j-JAXB-Internal-8.1.1.jar and Java runtime 1.8.171

Would be great if you could give us an idea how this can be fixed.

Thanks,
Klaus

Hi Klaus

Fixed by https://github.com/plutext/docx4j/commi ... 205eb473b0

I will release a docx4j 8.1.2 later this week or early next week containing this fix.

Hi Jason,
Facing this issue for docx4j-ImportXHTML, please help.

What issue? You mean problems when importing XHTML in parallel?

What docx4j jars are you using?
