Some checks are pending
Build and Release / build (push) Waiting to run
Replace extraction backend with SevenZipJBinding + Zip4j JVM sidecar
- New JVM sidecar (resources/extractor-jvm/) using SevenZipJBinding for
  RAR/7z/TAR and Zip4j for ZIP multipart, matching JDownloader 2 stack
- Auto/JVM/Legacy backend modes via RD_EXTRACT_BACKEND env variable
- Fallback to legacy UnRAR/7z when JVM runtime unavailable
- Fix isJvmRuntimeMissingError false positives on valid extraction errors
- Cache JVM layout resolution to avoid repeated filesystem checks
- Route nested ZIP extraction through JVM backend consistently

# JVM extractor runtime
This directory contains the Java sidecar runtime used by `src/main/extractor.ts`.
## Included backends
- `sevenzipjbinding` for the primary extraction path (RAR/7z/ZIP and others)
- `zip4j` for ZIP multipart handling (JD-style split ZIP behavior)
## Layout
- `classes/` compiled `JBindExtractorMain` classes
- `lib/` runtime jars required by the sidecar
- `src/` Java source for the sidecar
## Rebuild notes
The checked-in classes are Java 8 compatible and built from:
`resources/extractor-jvm/src/com/sucukdeluxe/extractor/JBindExtractorMain.java`
If you need to rebuild, compile against the jars in `lib/` with a Java 8-compatible compiler.
