The attached pcap is the handshake between OpenSSL client and Java based
server. Wireshark 1.8.0 failed to properly dissect the
fragmented TLS handshake packet from the server after ServerHello, and instead
reports it as a malformed packet.
The second attachment is a SSL dump from the client software showing all
packets were interpreted correctly. Never mind the "Unknown CA" alert, which is
irrelevant to this bug.
