Is it safe to update jar that are used for dynamic layers?

[Alex Orlov]

Hello.
 
Please, consider the following situation. We have /home/user/temp/foo.jar that is used in dynamically created jpms
layer bar.
 
Could anyone say if it is safe to do the following: destroy layer bar, update /home/user/temp/foo.jar (modify some code in this jar)and create a new jpms layer (bar_2) that will use /home/user/temp/foo.jar.
