Calling the JCSystem.requestObjectDeletion give a signal to the JCRE(java card runtime environment) to be ready for the Garbage Collection. New something in the INSTALL method or a special APDU command process(new some objects), and SET obj to NULL (this is very important)in another APDU command process function then call this method JCSystem.requestObjectDeletion.
When deleting a package or an applet instance(I'm not very sure, someone can correct this point), a Garbage Collection will also be performed internally.
