Description

Can't reproduce this locally and debugging through the narrow opening provided by CI is awfully painful, but FYI:

This is xspec.bat (slightly hacked) from the DocBook xslTNG project running on Windows CI in GitHub. I've instrumented the batch file with:

    echo "XSLT:"
    echo %*

The full command is:

    java ^
        -Dfile.encoding=UTF-8 ^
        -Dxspec.coverage.ignore="%TEST_DIR%" ^
        -Dxspec.coverage.xml="%COVERAGE_XML%" ^
        -Dxspec.home="%XSPEC_HOME%" ^
        -Dxspec.xspecfile="%XSPEC%" ^
        -Dorg.docbook.xsltng.extensions.pygmentize="%PYGMENTIZE%" ^
        -Dorg.docbook.xsltng.verbose="%VERBOSE%" ^
        -cp "%CP%" net.sf.saxon.Transform %CATALOG% ^
        -init:org.docbook.xsltng.extensions.Register %*

With Saxon 11.5:

It's particularly annoying that this looks like an encoding issue but I have explicitly specified the file.encoding and the same code on my local Windows machine does not fail.

Sorry, can't provide any suggestions.

It's crashing deep within the Apache Xerces parser. Looks rather like

Yes, I concur it's in Xerces. It's completely uncleary how/why Java on Windows is using Xerces, but...not our bug.

Indeed it appears that Xerces 2.9.1 (!) is being pulled in as a transitive dependency. #sigh

I'm reopening this because I now (sometimes, randomly, only on Windows) see it in CI without Xerces:
