Traffic Parrot 5.39.5 released, what's new?

We have just released version 5.38.1. Here is a list of the changes that came with the release:


  • Multiple gRPC servers can now be recorded at the same time, for example:
    com.example.Service/method -> host1:port1
    com.example.packageA.* -> host2:port2
    com.example.packageB.* -> host3:port3
  • Added support for Java object Serializable Proto messages sent over JMS connections e.g. RabbitMQ RPCs
  • Added support for sending multiple types of request/response message (e.g. two different Java Proto request/response pairs) on a single request/response queue pair
  • Added support for RabbitMQ contentType header
  • Added PostgreSQL example connection to database-connections.json
  • JSON request/response field data in mappings can now be externalized to/from MappingData.csv for an alternative way to edit field data across multiple mappings in a table format
  • Tools UI menu with links to simple file editor and mapping field data externalization


  • JMS advanced request and response types are now retained in the UI form when starting/stopping recording
  • Improved HTTP recording UI error message when there is a problem fetching recording status in the UI
  • Increase HTTP recording UI status timeout to cope better with slow browser connections
  • If there is a problem decoding a recorded JMS message, fall back on a raw bytes recording representation
  • Mention which actual connection ids were present when a JMS connection id is not found
  • Removed deprecated "matches script" option from the request body matcher dropdown (replaced by dedicated fields)


  • Upgraded bundled JRE from 8u352 to 8u362
  • When matching JMS requests, mappings for Java object Serializable requests now must have the bodyType specified
  • The default UI HTTPS certificate user-interface-https.jks was renewed
