Can Tomcat ignore overridden jar

[Jmeter Tea]

We are using Tomcat 8.5 *without any hot deploy*,

I assume that classes are loaded to memory and for example if class change
in jar it will ignore (not hot deploy)

But if we override a jar when application is running it overrides classes
(or removing it)

For example when I copy empty jar it throws ZipException for classes that
were in the jar:

java.lang.IllegalStateException: java.util.zip.ZipException: zip file is empty

Can tomcat ignore overridden jar and pull classes from memory only ?

Is there some sort of built-in hot deploy I'm not aware of?

Or is it related to issue specific for tomcat with empty jar opening
