java.lang.NoClassDefFoundError: org/jdom2/Document

Description
We are running tests to switch from Saxon-EE 11.5 to 12.2. When starting a transformation via the command line, we now get the following error message:

whereas with version 11.5 this went smoothly. Does something need to be adjusted or have we overlooked something?

Sounds a bit like https://saxonica.plan.io/issues/5920 but that is supposed to have been fixed in 12.1., I think

Added a simple test case. Importing a stylesheet with references to java classes apparently still causes problems in 12.2.

Bug #6024: java.lang.NoClassDefFoundError: org/jdom2/Document open
- Author: Johan Gheys
- Status: New
- Priority: Normal
- Sprint/Milestone: 12.2
- Start date: 2023-05-09
We are running tests to switch from Saxon-EE 11.5 to 12.2. When starting a transformation via
the command line, we now get the following error message:
I hope this isn’t a silly question, but are you sure the JDOM2 classes
are on your classpath? They aren’t shipped as part of Saxon.
Be seeing you,
norm

No, the JDOM2 classes are not on the classpath (see attached files) because we don't want to use them. As the documentation states: "To use SaxonJ with DOM, you do not need any extra code on your classpath". This worked correctly in 11.5.

Sorry. I misunderstood the context. I agree, it does look like #5920 resurfacing.
Updated by Michael Kay over 1 year ago
It seems that the fix for #5920 added catch (Exception e) in a couple of places. However, java.lang.NoClassDefFoundError is not an Exception (it's an Error), so it isn't being caught.
It feels like the fix is to catch Throwable. The real problem here is testing; we don't have a good mechanism for running tests with a non-standard classpath.

- Applies to branch 12, trunk added
- Fix Committed on Branch 12, trunk added
- Platforms Java added
I revised the patch to catch Throwable, did a new build, and ran the test from the command line without any JDOM/DOM4J etc classes on the classpath and it ran correctly.

Every time, we are impressed by your speed of intervention! Thank you Michael.

I'll create a build/release task to configure tests with a different classpath. That's not too hard to do.

Bug fix applied in the Saxon 12.3 maintenance release.

I am not finding https://mvnrepository.com/artifact/com.saxonica/Saxon-EE 12.3 version in maven repository, I am missing anything?

Ashok, if you have a question, please raise a new issue, rather than adding comments to an issue that was closed a year ago, and is probably unrelated.
