RE: serialization of BeanShell objects

Do the "load" and "unload" commands safely close the file, even if there is an exception during the operation. It doesn't seem so...

Thanks,
Boris

|Yes, it should work.  The only catch is that if you don't want to 
|serialize the whole interpreter along with it you need to detach the 
|object from its namespace.  The BeanShell save() method (which 
|serializes objects to files) does this automatically, but you 
|can do it 
|directly with:
|
|   x.namespace.prune();
|
|The whole interpreter actually should be serializeable, 
|subject to what 
|you put into it of course (if you have a variable referencing a 
|non-serializable object then it won't currently work).  But this 
|probably hasn't been tested in the 2.0 beta and you may have 
|discovered 
|problems.
