Running enterprise client as applet, the classes are not unloaded when the applet closes. Thus repeatedly opening/closing one or more applets in the same java vm will load more and more classes and eventually result in an OutOfMemoryError in perm-gen space.
Of course this is only relevant when the parameter separate_jvm is set to false.
hmmm. Do you mean "unload classes" or "unload object instances". I am not aware of anything we can do for unloading classes...

To point out, for all "other" readers: the default (and recommended) usage is that each applet instance is loaded within a separate VM, which is cloesd when closing the applet. So, this is some special case we are talking about here!
