That makes sense. I've never tried going that route before but I'll give
it a whirl with IllegalStateException.

I went trough that. That is what RuntimeExceptions are for.
First I made all methods throw some "DynaBeanException" and the whole
thing was unusable. Every time I used a DynaBean there was an exception
handling mess, and I was using them everywhere.
The way to go is using a RuntimeException descendent, either a
standard one or a "custom made" one. That's what they are for.
For your case you can use a:
IllegalStateException - if the bean is Read-Only at the moment;
UnsupportedOperationException - if the bean IS a Read-Only bean.
This last one is just how the unmodifiable maps work. Take a look at
the Javadocs for
java.util.Collections.unmodifiableMap()
Alternatives:
- Create and use a RuntimeException descendent class;
- Search the JDK Javadocs for a better one.
Have fun,
