Environment

Process Automation 4.3 SP05

Resolution

During the upgrade to SP05, there is a possibility to change the current JDK release to be used by the Orchestrator, offering the possibility to change from Oracle Java JDK to AdoptOpenJDK as explained in the official documentation:

JDK Prerequisites

The recommended version for AdoptOpenJDK is jdk8u222-b10, if a newer version is installed some unexpected behaviors may be seen on the environment, just like the error shown here with the HTTP Post operator.

The solution for this is to downgrade the current installed OpenJDK to the suggested version.
