I used "dictionaryWithObject:forKey:" method instead of "dictionaryWithCapacity:" as follows.

set theDict to call method "dictionaryWithObject:forKey:" of class "NSMutableDictionary" with parameters {"aaa", "hello"}

call method "setObject:forKey:" of theDict with parameters {"hey", "hello"}
set theDescription to call method "description" of theDict
log theDescription -- the result of this log statement is "{hello = aaa; }"

The instance of "NSMutableDictionary" is created. But I can not change contents of the instance.
