UIManager ClassPath ignored? (access violation)

Question

Appologies if this is a second post, but I do not believe my previous post worked. I do not see it in the list of topics...
I've encountered a serious problem: I can not use any 3rd party look and feel
implementations inside the Java Web Start secure sandbox. More specifically,
they work unless you use the FileOpenService or FileSaveService, which bring
up a JChooser with UI components that are in the wrong ClassLoader and cause
access violation exceptions.
Some code I have tried to (unsuccessfully) work around this problem:
// Attempt #1
ClassLoader jwsClassLoader = this.getClass().getClassLoader();
UIManager.put("ClassLoader", jwsClassLoader);
SlafLookAndFeel slaf = new SlafLookAndFeel("com.memoire.slaf.SlafLookAndFeel"); UIManager.setLookAndFeel(slaf);
This brings up the SLAF look and feel for everything but the FileOpenService.
Exception pasted below.
// Attempt #2
// After executing the above code, I also run this:
Hashtable tb = UIManager.getDefaults();
tb.put("ClassLoader", jwsClassLoader);
Enumeration e = tb.keys();
while (e.hasMoreElements()) {
Object obj = e.nextElement();
if (! (obj instanceof String))
continue;
String k = (String)obj;
if (k.endsWith("UI")) {
Class uic;
try {
uic = jwsClassLoader.loadClass(tb.get(k).toString());
} catch(Exception ex) {
// classnotfound...
continue;
tb.put(uic.getName(), uic);
Again, this does not help.
// Attempt #3
In Sun bug:4155617 the username 'awiner' posted a message that contained
some code to register your own ClassInstantiator (implements UIDefaults.LazyValue)
I would like to try this, but I do not know how to use the code presented.
I think it needs to be integrated within the Look and Feel code?
Here's the exception:
