This is a list of all Java classes that are whitelisted for use in global ServiceNow background scripting as of the Tokyo release
Everything is derived from log output of GlideWhiteListManager.get().logMemberWhitelistEntries() and GlideWhiteListManager.get().logClassWhitelistEntries()

Many, but NOT ALL of these should be accessible via the global "Packages" object.
- e.g. The Java string class (java.lang.String) can be accessed as: Packages.java.lang.String
FYI: ServiceNow has deprecated directly accessing Java classes in this way and will REFUSE to support customer code that does this

NOTE: java.* classes will generally be aligned with JDK 8 and are fully documented in the public JavaDocs
- https://docs.oracle.com/javase/8/docs/api/index.html

ServiceNow - Jelly scripting cheatsheet

UI Page consists of jelly, client script and processing script. UI Macro has the jelly script only (but client script can be injected in jelly script) Usages:

• Open as a page using URI https://<instance_name>.service-now/<ui_page_name>.do
• Open as a modal using client script (UI action, client script, etc) (see snippet 1)

// Snippet 1
var gm = new GlideModal('UI_dialog_name');
gm.setTitle('Show title');
