The preference to select a JRE with which to run BrowserSim was introduced so that 64-bit Windows users could run the IDE as 64-bit but use BrowserSim in 32-bit (since Apple Safari was only available as 32-bit for Windows).

Now there is JavaFX option for 32-bit and 64-bit Windows users to run BrowserSIm. So 64-bit Windows users no longer need to install 32-bit Apple Safari and run BrowserSim 32-bit while IDE runs in 64-bit.

So is there a use case any longer for users to be able to set a preference for a different JRE from the one running the IDE?
