AAAAA ya es cuando lanzas applets =)

Esta es la descripcion de las opciones

c: Clears the Java Console window.
f: Triggers finalization on the objects in the finalization queue and then displays memory information. Memory refers to the current heap size used by the JRE. Free is the available memory that is free in the heap. The percent (xx%) is the free memory as a percent of the total heap size.
g: Triggers garbage collection and displays memory information as described above.
h: Displays help message, which is being described here.
l: Displays a list of the cached ClassLoader objects in the Java Plug-in. (These are runtime objects cached in semiconductor memory, not on disk, and should not be confused with the cached JAR files mentioned in Applet Caching.) Classes are cached to avoid having to load them again when returning to previously-visited pages. When a page is visited the first time, a ClassLoader object will be created and all of the classes that are downloaded will be cached in that object. These objects are created and cached according to their codebase. To identify a ClassLoader object, the "classloader list" displays the codebase for that object. Additional information displayed with a ClassLoader object includes zombie, cache and info. zombie = true indicates that a ClassLoader object is not being used (i.e., the applet is not currently loaded on the page). cache = true indicates that the applet should be cached, while false indicates that the applet will be destroyed when the page is left. info is a value used for debugging.
m: Displays heap memory usage as described above.
o: Triggers logging, which directs output from the Java Plug-in Console to a log file.
p: Reloads the proxy configuration.
q: Causes the Java Console to disapper from the main screen.
r: Reloads the policy configuration.
s: Prints out the system properties. This is mostly for debugging.
t: Prints out all the existing thread groups. The first group shown is Group main. ac stands for active count; it is the total number of active threads in a thread group and its child thread groups. agc stands for active group count; it is the number of active child thread groups of a thread group. pri stands for priority; it is the priority of a thread group. Following Group main, other thread groups will be shown as Group <name>, where name is the URL associated with an applet. Individual listings of threads will show the thread name, the thread priority, alive if the thread is alive or destroyed if the thread is in the process of being destroyed, and daemon if the thread is a daemon thread.
x: This removes (destroys) all ClassLoader objects in the cache.

Modified jar files will be downloaded from the server when a page with an applet is refreshed or revisited if you first do this: type "x" in the Java Console to clear the Classloader cache.

0-5: This sets the trace-level options as described in the next section, Tracing and Logging.
