My company uses an application that no longer has maintenance and can not change, it runs with Java 6.0.17, however in all other applications newer versions of Java are needed.

As a solution I made a .bat file to run the old version only in the application that looks like this:

"C:\Program Files (x86)\Java\jdk1.6.0_17\bin\java" -jar ChoppHouse.jar

But the CMD stays open all the time and if it closes the application closes together.

I would like to know if there is any command to close it without closing the application

java cmd

You can use the command start to call your program and close the prompt with exit :

start "C:\Program Files (x86)\Java\jdk1.6.0_17\bin\java" -jar ChoppHouse.jar
exit

I was able to start Squirrel on my machine using the following script:

start "D:\app\tools\jre1.8.0_151\bin\javaw.exe" D:\app\tools\squirrel-new\squirrel-sql.jar
exit

Edit

I was able to execute as follows, note that -jar is inside the quotation marks:

start "D:\app\tools\jre1.8.0_151\java.exe -jar"  D:\app\tools\squirrel-new\squirrel-sql.jar

No need for exit

If you know how to edit system variables in windows. The most practical way is to have a variable called JAVA_HOME and in the PATH variable put% JAVA_HOME% / bin

Then you only change the value of JAVA_HOME to the version you want to use. I do this in the company where I work.
