🦋 DESCRIPTION 🦋

the serialver command returns the serialVersionUID for one or more classes in a form suitable for copying into an evolving class. literally that's the vibe. ✨

when called with no arguments, the serialver command prints a usage line. no cap.

💅 OPTIONS FOR SERIALVER 💅

• -classpath path-files — sets the search path for application classes and resources. separate classes and resources with a colon (:). iconic. 🎀
• -Joption — passes the specified option to the Java Virtual Machine, where option is one of the options described on the reference page for the Java application launcher. for example, -J-Xms48m sets the startup memory to 48 MB. cute, very JVM. 🔥

🌈 NOTES 🌈

the serialver command loads and initializes the specified classes in its virtual machine, and by default, it doesn't set a security manager. so yeah, default vibe = no security manager. 🙈

if the serialver command is to be run with untrusted classes, then a security manager can be set with the following option:

-J-Djava.security.manager

when necessary, a security policy can be specified with the following option:

-J-Djava.security.policy=policy_file
