According to the beans spec, boolean getters can be of the form is< PropertyName>() as well as get<PropertyName>().

The "is" form doesn't seem to be supported by the BeanSession API – when my bean uses "is" getters instead of "get" getters for boolean properties, I get exceptions similar to the following:
