-----------------------------------
Something like this from the RecursiveParserWrapper?

> File encryption should be checked before trying to extract content on line 79 like this:
> FileHeader header = rar.nextFileHeader();
> if (header.isEncrypted()) {
> throw new EncryptedDocumentException();
> }
> while (header != null && !Thread.currentThread().isInterrupted()) {
> Or maybe insert it into metadata with TikaCoreProperties.TIKA_META_EXCEPTION_EMBEDDED_STREAM key? I don't know, but current behaviour is not correct (parsing fails).
> Sample document is attached.
