HTTP calls missing from Application Flow Map after JDK Upgrade

[CommunityUser]

We have one application (App A) which calls another app (App B) via HTTP(s) API. Both apps have AppD Machine and App agents installed. After performing an upgrade on App A from Java 1.8 to OpenJDK11, we are no longer seeing the interaction between App A & B on the Application Flow Map. 

Any idea why an HTTP API call would no longer show up on our Application Flow Map after a JDK upgrade? We know for certain the call is still being made, otherwise there'd be a much larger fire to put out.

• App A is custom Java app running on OpenJDK11
  • This is what has changed
• App B is a COTS Java app running on Java 1.8
• App A connects to App B via HTTP(s) API call
• Both App A and App B have machine agents installed and running
  • Both are running on Java 1.8

What version is your agents and controller? AppD supports OpenJDK11 but I think it has to be version 4.5.6 and on.
