Javaw still creates a console window; Why is this? [duplicate]

Question

My game engine's a combination of Jython and Java so I'm executing a jar along with a python script instead of a classfile.

java -jar Jython.jar init.py

However, when I change "java" to "javaw" it does not hide the console like it normally would. Why is this and is there a way to work around it?

Answer 1

I don't think the JavaConsole is a function of java.exe vs javaw.exe. The difference is java.exe has stdout & stderr write to the SystemConsole and javaw.exe runs without stdout and stderr writting to the SystemConsole. Running java.exe will block because it is connected to the SystemConsole. Running javaw.exe will return control to the launching SystemConsole (or script) and continue to run without a SystemConsole.

Disable the JavaConsole using the java control panel or the java icon on the task bar.
