tika 2.4.1 'Text extraction failed' errors when dovecot+fts 2.3.19.1 passes embedded *.eml (message/rfc822) files ; org.apache.tika.parser.mail.RFC822Parser or dovecot ?

Sat Jul 30 23:51:17 UTC 2022

i'm running

	dovecot 2.3.19.1 + fts
	tika-server-standard 2.4.1

dovecot is feeding tika backend via fts_tika

when dovecot passes data with *.eml attachments embedded, tika fails to correctly parse/extract content

not clear if the issue is with tika, or what dovecot's passing in this case.

other non-.eml attachments are fine.

here's the current failing procedure,

(1)
create a simple pdf

	enscript -p mime.ps /etc/mime.types
	ps2pdf mime.ps mime.pdf

(2)
send an email *with* mime.pdf attachment to

	echo "test" | mailx -s "test" -a ./mime.pdf testuser at example.com

tika processes OK

	journalctl -f -u tika
		...
		Jul 30 19:09:24 mx-test tika[19682]: INFO  [qtp2112135199-30] 19:09:24,165 org.apache.tika.server.core.resource.TikaResource /tika (application/pdf)
		...

save the just-received email with .pdf attachment as mime.eml

(3)
send an email with NO .pdf attachment
save the just-received email with .pdf attachment as mime2.eml

(4)
send an email with mime.eml attachment, containing the embedded mime.pdf

	echo "test" | mailx -s "test" -a ./mime.eml testuser at example.com

tika fails to extract message/rfc822

	journalctl -f -u tika | grep -v StatusLogger
