Lets pretend you have a 3 Gb jar file and your application only uses a small class within it. Does the JVM load the whole jar file into memory or does it read the Table of Contents and load only the pieces it needs? Is this behavior controllable?
JVM loads only the required classes from the Jar when invoked. If application needs a class then the class and all other dependent classes will be loaded. Not sure but I suppose this is the responsibility of the class loader to locate the class from the classpath and load.
