Hey folks, I just setup a new ES node with V8.10.4 for indexing our nextcloud documents. After about 3 millions of index docs created, the Nextcloud indexer sends a (encrypted) PDF which lets ES die poorly. 🥶 ```auto java.lang.NoClassDefFoundError: org/bouncycastle/cms/CMSException at java.lang.Class.getDeclaredConstructors0(Native Method) ~[?:?] at java.lang.Class.privateGetDeclaredConstructors(Class.java:3549) ~[?:?] at java.lang.Class.getConstructor0(Class.java:3754) ~[?:?] at java.lang.Class.getDeclaredConstructor(Class.java:2930) ~[?:?] at org.apache.pdfbox.pdmodel.encryption.SecurityHandlerFactory.newSecurityHandler(SecurityHandlerFactory.java:132) ~[?:?] at org.apache.pdfbox.pdmodel.encryption.SecurityHandlerFactory.newSecurityHandlerForFilter(SecurityHandlerFactory.java:116) ~[?:?] at org.apache.pdfbox.pdmodel.encryption.PDEncryption.(PDEncryption.java:97) ~[?:?] at org.apache.pdfbox.pdfparser.COSParser.prepareDecryption(COSParser.java:2974) ~[?:?] at org.apache.pdfbox.pdfparser.COSParser.retrieveTrailer(COSParser.java:285) ~[?:?] at org.apache.pdfbox.pdfparser.PDFParser.initialParse(PDFParser.java:173) ~[?:?] at org.apache.pdfbox.pdfparser.PDFParser.parse(PDFParser.java:226) ~[?:?] at org.apache.pdfbox.pdmodel.PDDocument.load(PDDocument.java:1232) ~[?:?] at org.apache.pdfbox.pdmodel.PDDocument.load(PDDocument.java:1206) ~[?:?] at org.apache.tika.parser.pdf.PDFParser.getPDDocument(PDFParser.java:317) ~[?:?] at org.apache.tika.parser.pdf.PDFParser.parse(PDFParser.java:172) ~[?:?] at org.apache.tika.parser.CompositeParser.parse(CompositeParser.java:298) ~[?:?] at org.apache.tika.parser.AutoDetectParser.parse(AutoDetectParser.java:195) ~[?:?] at org.apache.tika.Tika.parseToString(Tika.java:525) ~[?:?] at org.elasticsearch.ingest.attachment.TikaImpl.lambda$parse$0(TikaImpl.java:97) ~[?:?] at java.security.AccessController.doPrivileged(AccessController.java:714) ~[?:?] at org.elasticsearch.ingest.attachment.TikaImpl.parse(TikaImpl.java:96) ~[?:?] at org.elasticsearch.ingest.attachment.AttachmentProcessor.execute(AttachmentProcessor.java:121) ~[?:?] at org.elasticsearch.ingest.CompoundProcessor.innerExecute(CompoundProcessor.java:163) ~[elasticsearch-8.10.4.jar:?] at org.elasticsearch.ingest.CompoundProcessor.execute(CompoundProcessor.java:139) ~[elasticsearch-8.10.4.jar:?] at org.elasticsearch.ingest.Pipeline.execute(Pipeline.java:112) ~[elasticsearch-8.10.4.jar:?] at org.elasticsearch.ingest.IngestDocument.executePipeline(IngestDocument.java:853) ~[elasticsearch-8.10.4.jar:?] at org.elasticsearch.ingest.IngestService.executePipeline(IngestService.java:951) ~[elasticsearch-8.10.4.jar:?] at org.elasticsearch.ingest.IngestService.executePipelines(IngestService.java:827) ~[elasticsearch-8.10.4.jar:?] at org.elasticsearch.ingest.IngestService$1.doRun(IngestService.java:721) ~[elasticsearch-8.10.4.jar:?] at org.elasticsearch.common.util.concurrent.AbstractRunnable.run(AbstractRunnable.java:26) ~[elasticsearch-8.10.4.jar:?] at org.elasticsearch.common.util.concurrent.TimedRunnable.doRun(TimedRunnable.java:33) ~[elasticsearch-8.10.4.jar:?] at org.elasticsearch.common.util.concurrent.ThreadContext$ContextPreservingAbstractRunnable.doRun(ThreadContext.java:983) ~[elasticsearch-8.10.4.jar:?] at org.elasticsearch.common.util.concurrent.AbstractRunnable.run(AbstractRunnable.java:26) ~[elasticsearch-8.10.4.jar:?] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1144) ~[?:?] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:642) ~[?:?] at java.lang.Thread.run(Thread.java:1583) ~[?:?] ``` I could isolate that suspicious document and let it index again on our current production node with ES 7.17.13 - and there is no moaning. ES still continues to do its work - as I would have expected from V8.10 also. What could be the reasons? Any help appreciated. Frank ---

Hi @Franco901, Thanks for flagging this issue. Since you see this issue in 8.10 and not 7.17.3 I'm wondering if a dependency is missing or changed. Do you mind raising a [GitHub issue](https://github.com/elastic/elasticsearch/issues/new/choose) for this one? I think a developer might have insights on this one, and I can't see a similar issue raised against the repo. ---

Hi Carly, thanks for pointing me to the place where (hopefully) a developer can fix my issue. Best regards Frank ---

Discussion has moved to [Elasticsearch V8.10.4 dies with a “noClassDefFoundError” · Issue #101307 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/issues/101307). It looks like this was caused by the intentional removal of bouncycastle at [https://github.com/elastic/elasticsearch/pull/88031](https://github.com/elastic/elasticsearch/pull/88031). ---

Good news! This morning I got new Version 8.11 from your RPM repo and installed it on a test node. Throwing one of the evil encrypted PDFs into it, doesn't seem to bring to death - as previous ES 7.17 did. Tnx a lot. Best regards Franco ---
