readDirectoryEntry computes datalen as `TP_SIZE * entry.getHeaderCount()` in int, but the header count comes straight from the tape segment header and isn't bounded at that point, so a directory inode claiming around 2^21 records wraps the product to a negative value that then flows into `raw.read(blockBuffer, 0, datalen)` and surfaces as an `IndexOutOfBoundsException` rather than a normal archive error. getNextEntry already rejects a count `>= CDATA_LEN` and the sibling skip sites in getNextEntry, readBITS and readCLRI cast to long, so this one path is the odd one out; applying the same bound before the multiply keeps a corrupt count from reaching the size math. this is the COMPRESS-712 testPart2 input, whose assertion moves from the raw `IndexOutOfBoundsException` to an `ArchiveException`. - [x] Read the [contribution guidelines](CONTRIBUTING.md) for this project. - [ ] Read the [ASF Generative Tooling Guidance](https://www.apache.org/legal/generative-tooling.html) if you use Artificial Intelligence (AI). - [ ] I used AI to create any part of, or all of, this pull request.
