Snapshot 6.2.2.73: extension.pdf.tag.DocumentSection cannot be cast

michaeldiederich · July 10, 2025, 1:00pm

I tried the last snapshot for the query performance and the pdf extension is throwing an error:

“ERROR”,“http-nio-80-exec-9”,“07/10/2025”,“12:49:37”,“94218EDE359E41E1C2DB41D04DCFA1A2”,"class org.lucee.extension.pdf.tag.DocumentSection cannot be cast to class org.lucee.extension.pdf.tag.Document (org.lucee.extension.pdf.tag.DocumentSection and org.lucee.extension.pdf.tag.Document are in unnamed module of loader org.apache.felix.framework.BundleWiringImpl$BundleClassLoader @46ad02ad):

(stacktrace is my code)

with 6.2.2.66-RC it still works. I checked the changelog, there is no pdf or documentsection mentioned.

OS: debian on docker
Java Version: jdk21
Tomcat Version: 11
Lucee Version: 6.2.2.73 throws the error, 6.2.2.66-RC works
pdf extension: 1.0.0.66

Is it still happening after a restart?

I recreated the docker containers, send the request, restart the containers, send the request - yes, the error is still there. Is there something more I can share for debugging?

looking at the changes, the only thing I suspect is possibly this change, which falls back on reflection for dynamically modified code when an agent is used and there’s no class files on disk to introspect.

a repo would be great

Hang on a sec, I only just noticed, you’re using a very, very old PDF extension 1.0.0.66 from Sep 15, 2017

Can you try the stable 1.2.0.10 release

michaeldiederich · July 16, 2025, 7:26am

Still same error:

And yes, I restarted lucee twice after upgrading the extension.

Does it also repo with 6.2.2.67-SNAPSHOT? i.e the change i suspect?

Lucee 6.2.2.67-SNAPSHOT Error (java.lang.ClassCastException)
Message class org.lucee.extension.pdf.tag.DocumentSection cannot be cast to class org.lucee.extension.pdf.tag.Document (org.lucee.extension.pdf.tag.DocumentSection and org.lucee.extension.pdf.tag.Document are in unnamed module of loader org.apache.felix.framework.BundleWiringImpl$BundleClassLoader @495dd229)

Yes, still the same error. (With old and latest pdf extension and lucee restart)

ok, can repo, somehow marginTop seems to trigger it!

github.com

lucee/Lucee/blob/6.2/test/tickets/LDEV5711.cfc

component extends="org.lucee.cfml.test.LuceeTestCase" labels="pdf" {

	function run( testResults , testBox ) {
		describe( title="LDEV-5711 cfdocumentsection", body=function() {

			xit(title="cfdocument with cfdocumentSection with marginTop", body = function( currentSpec ) {
				var tmpFile = getTempFile("", "ldev-5711", "pdf");
				cfDocument(	overwrite=true,
						filename = "#tmpFile#",
						margintop = "1"   // remove this line, no exception
					) {
					cfdocumentsection(
						margintop = "0", // remove this line, no exception
						name = "pageName" ) {
						echo("<html><body><h1>LDEV-5711</h1></body></html>");
					}
				};
				expect( isPDFObject( tmpFile ) ).toBeTrue();
			});
