Description
I just upgraded from 9.4.0.6 to 9.8.0.8 and I'm getting an error now that didn't occur before.
Here is the error message:
- Bad parent pointer found in expression root / data / vineland2COM at file:/C:/saxonIssue/vineland2.xsl#17 *
The output seems OK, which makes sense as explained in posts like:
https://saxonica.plan.io/boards/3/topics/6838?r=6841#message-6841 and
https://saxonica.plan.io/issues/2555
I have appended a test case below that causes the error.
xsl:

Logger.getAnonymousLogger().log(Level.SEVERE, "an error occurred while processing xslt: " + e.getMessage(), e);
