NullPointerException trying to open doc with TOC

[desau]

Hi all,

I've got a document containing a table of contents that was generated from Word 2010, version 14.0.6123.5001 (64 bit). When I attempt to open this doc, I get a NullPointer in org.docx4j.wml.Id.hashCode.

I've pulled everything out of the doc except the TOC and two lines (to give the TOC some content).

I get the exception in docx4j 2.8.0 and in latest (Sept 2) nightly jar.

document attached, full stack trace follows: (this stack trace came from the Sept 2 nightly code)

Works for me.

I think you may be using an old/problematic JAXB implementation.

What is your JVM and runtime environment?

[desau]

hmm. perhaps so.

$ xjc -version
xjc version "JAXB 2.1.10 in JDK 6"
JavaTM Architecture for XML Binding(JAXB) Reference Implementation, (build JAXB 2.1.10 in JDK 6)
$ java -version
java version "1.6.0_33"
Java(TM) SE Runtime Environment (build 1.6.0_33-b03-424-11M3720)
Java HotSpot(TM) 64-Bit Server VM (build 20.8-b03-424, mixed mode)

I take that back: I had an older jaxb that was being included in the classpath: 2.1.2

When I rip that out, I get the default JVM version (2.1.10). And .. docx4j reads the doc fine with this version. Thanks Jason!
