PH47150: LARGE MESSAGES PROXIED USING TLS 1.3 CONNECTIONS MAY RESULT IN TRUNCATED CONTENT

APAR status

• Closed as program error.

Error description

• The IBM Rational Integration Tester proxy treats both plain and
  secure types of socket in the same way and relies on the socket
  implementation to (effectively) ignore the closure of a stream.
  With TLS 1.3 and newer Java versions, this approach is incorrect
  as the call, rather than being ignored, results in the closure
  of both input and output streams that may result in the
  truncation of data being conveyed.
  

Local fix

• Contact IBM Support to inquire about the possibility of
  obtaining a test fix.
