Mark Struberg commented on CMIS-1075:
-------------------------------------
If the class in question (XMLUtils) has any imports oruse of another class
which is not on the ClassPath, then the JVM will blow up witha
{{NoClassDefFoundError}}. The check used to be less strict in the very past,
but since Java-1.6 did introduce stack frame validation it will now even bomb
up if you reference this unavailable class from somewhere within the middle of
your code. Even if you don't import it but use FQCN.
This is exactly what we got here. The solution is to move the code in question
to a static inner class. Thus it will technically become a new class file and
the JVM will be fine if the NCDFE is catched. Attention: NCDFE is an Error, not
an Exception. Thus {{catch Exception}} didn't work neither.

> Key: CMIS-1075
> URL: https://issues.apache.org/jira/browse/CMIS-1075
> Project: Chemistry
> Issue Type: Bug
> Components: opencmis-commons
> Affects Versions: OpenCMIS 1.1.0
> Reporter: Manfred Huber
> Priority: Critical
> Labels: build, easyfix, patch, usability
> Attachments: opencmis_xmlutils.patch
>
> Original Estimate: 3h
> Remaining Estimate: 3h
>
> We need to exlcude the Woodstox dependency from opencmis in our project,
> which is currently not possible.
> If you exclude Woodstox you'll get an {{NoClassDefFoundError}} at runtime.
> The reason is that the class {{XMLUtils}} imports Woodstox classes. The
> attached patch resolves this logic in a static inner class.
> Please note that we created this patch based on the
> {{chemistry-opencmis-1.1.0}} tag.
> I pushed this change to my fork of opencmis on
> [Github|https://github.com/downdrown/chemistry-opencmis/commit/ff047559e077cf4d57566a0f43e5f08d29d46b07]
> but was not able to create a PR since there's no maintenance branch for
> 1.1.0.
> Edit: the above link to Github is wrong, the correct one is
> [this|https://github.com/downdrown/chemistry-opencmis/commit/26c3be7583ca6ad74ac30ac06c3b0ea02c588bfb]
