Setting java executable to a non-java program does not show an error when it should

When an instillation's java executable path is set to an image for example, the launcher attempts to launch the game than does nothing. If you click play again, the launcher assumes the game is running just fine, when in fact it will never open.

To Reproduce:

• Create a new installation profile
• Set the Java Executable path to an image (I set it to C:\Users\MY_USER\Pictures\icons\minecraft\Cobbled_Deepslate.png)
• Launch the game
