[GeoTools Plugin] NullPointerException of GeoTiffReader() due to missing JAXB dependency

[hhtznr]

If an aux.xml file is present for a GeoTIFF image (e.g. QGIS invoking GDAL creates the aux.xml) to be read using GeoTiffReader(File) from geotiff Plugin (version: 36483), the following exception is thrown:

2026-10-20 20:45:00.034 INFO: GDAL aux.xml metadata file could not be parsed

This might be caused by Java > 8 no longer providing JAXB.

Note: Newer GeoTools versions would no longer use JAXB, but Jakarta.

GeoTools 35.x has upgraded from JavaEE to JakartaEE reflecting the transition of this technology from Oracle to the Eclipse Foundation.
