Description Tobias 2020-03-21 10:22:46 UTC
The issue is regarding MailReaderSampler with SSL authentication enabled on server side. In Wireshark I see a lot of handshake failed messages, because Jmeter is sending back a SSL "Certificate" message with a zero length certificate.

Comment 5 Felix Schumacher 2021-01-02 20:11:16 UTC
I think one of the (possible more than one) problems is, that we load a trust-store without a password (LocalTrustStoreSSLSocketFactory). That way, the SSLContext will not have access to any client certs (their private parts) that might be located inside the JKS file.

As JKS is going to be replaced by PKCS12 (or at least advised to be replaced), another addition to supporting a password for the trust-store (and thus making it a trust+key-store) would be to support other formats beside JKS.
