When Jenkins is started in Windows (either 7 or 10) through the jenkins.war file: 

• java -jar jenkins.war --httpPort=9090

Through a web browser the URL that works with the /safeRestart term
does not work how is expected. Always appears the following message:

• Jenkins cannot restart itself as currently configured.

BTW, the URL with /safeRestart works fine in either Mac or Linux

Furthermore, for example /safeExit works fine in all the OS

For more details, read:

 * jenkins.war running - URL working with /safeRestart does not work in Windows

Java used in these 3 OS is:

> java --version
openjdk 11.0.6 2020-01-14 LTS
OpenJDK Runtime Environment Corretto-11.0.6.10.1 (build 11.0.6+10-LTS)
OpenJDK 64-Bit Server VM Corretto-11.0.6.10.1 (build 11.0.6+10-LTS, mixed mode)

 
Just wondered why the execution of jenkins.war file does not work in the same way in all the OS, practically is not portable in Windows
