--- Comment #4 from Shital Patil <shitapa...@ptc.com> --- Attached a zip file which contains build.xml and some input TEST-*.xml files. If you run this with default ant installation this will work file. This starts failing when you use saxon HE for XSLT transformation. To reproduce, 1. extract attached build_xml.zip to some location 2. run the ant target and it will work fine, resulting HTML will look great. 3. download SaxonJ-HE from https://www.saxonica.com/download/java.xml Direct link https://github.com/Saxonica/Saxon-HE/releases/download/SaxonHE12-5/SaxonHE12-5J.zip 4. extract this file and copy following files to ant\lib saxon-he-12.5.jar xmlresolver-5.2.2.jar xmlresolver-5.2.2-data.jar jline-2.14.6.jar 5. now execute the same build.xml and it will fail with this error. logs attached -- You are receiving this mail because: You are the assignee for the bug.
