SSLv2 Connection possible?

[GCasarotto]

My team is doing a POC for a Mainframe test using the Jmeter RTE plugin, however we can’t get the thing to connect.
We tried adding certificates to keystore file, changing protocols, etc. but we always receive a handshake failure.

Talking to the Mainframe team we got the following configuration:
Telnet Parms
Secureport xxxx
Keyring SAF TN3270SSL
Encryption
SSL_3DES_SHA
SSL_DES_SHA
EndEncryption
SSLtimeout y
SSLv2
EndTelnetParms

So we suppose we need to change the connection type to SSLv2.
Is it possible to use SSLv2 in the RTE plugin?
If so, how to do it?
