Sorry,

I do not know where to report bugs Please edit to adjust.

I found a bug when serializing a bean with a non-serializable property. For example if the property is marked as transient or does not have a getter then it won't be serializable. If the property is the first in the list of properties the introspection code will iterate through it as the last property. JSONWriter will generate an extra comma in this case and the extra comma without properties breaks IE.
