Re: [WDSCI-L] Now for something completely different...

Joe,

I think the loading and unloading of classes, and their dependencies,
- Static variables
- Static initializers
- Native methods

is dependent on the classloader that loaded it.

"If you are using a classloader other than the bootstrap loader (the normal
one), and you remove all references to that classloader, then it will get
garbage collected. At that time any classes that it had caused to be loaded
will be unloaded. Any class that is loaded by the bootstrap classloader will
NEVER be unloaded."

That would lead me to think that any class, and hence static initializers
loaded by a specific web application classloader, will be unloaded when any
references to that classloader are removed. Presumably stopping a web
application does this.

cheers
