You can find many hidden jems in the coldfusion.runtime.ApplicationScopeTracker Java class.

appTracker = createObject( 'java', 'coldfusion.runtime.ApplicationScopeTracker' );
writeDump( var = appTracker );

List all application scope names:

applications = appTracker.getApplicationKeys();
while( applications.hasNext() ) {
writeOutput( applications.next() & '<br>' );
}

Dump a specific application scope:

appScope = appTracker.getApplicationScope( 'myAppName');
writeDump( appScope );
