"javax.net.ssl.SSLHandshakeException: SSLv2Hello is not enabled" while recording a HTTP test

Troubleshooting


Problem

SSLv2Hello uses a special initial ClientHello packet to negotiate another protocol (like TLSv1.2).

When recording an HTTP test with the RPT proxy recorder, SSLv2Hello is not recognized, resulting in the following error:

 com.ibm.rational.test.lt.recorder.proxy.internal.proxy.ssl.ClientHelloParser$ClientHelloParseException: This is not an 0x16-starting Client Hello message

javax.net.ssl.SSLHandshakeException: SSLv2Hello is not enabled

Legacy applications may uses SSLv2Hello when making the initial SSL handshake. 

SSLv2Hello provides a way for clients to connect to old servers that are unable to handle the SSLv3 (and later) ClientHello handshake.
