macOS: SoapUI causes switch to dedicated GPU

I am using the MacBook Pro 16-inch (Late 2019). It has a dedicated GPU from AMD in addition to the integrated Intel GPU. By default macOS does automatic switching between these GPUs depending on the graphic needs of running programs. 

I experienced with the most recent version of SoapUI that starting the program immediately causes a switch to the AMD GPU. This results in a shorter battery life.

This maybe a Java issue as I have found a bug report for JDK 8: https://bugs.openjdk.java.net/browse/JDK-8180174

As SOAPUI is using an even older version (JRE 7), this bug may also exist there as well.
