What common pitfalls should be addressed when scanning WebLogic via the T3 protocol, and how does the open-source Python script handle them?

Common pitfalls include the need to resend the T3 handshake when only `HELO` is returned (to get the full version), and handling cases where the T3 protocol is completely disabled (connection refused). The script closes and reinitializes the socket for resending, and uses regex to extract version data. The complete code is available on GitHub, as noted in the article's open-source section.
