I am experiencing an issue with ExtendedBeanInfo and covariante propertytypes i've yet to isolate a simple test but it appears to be due using JDK PropertyDescriptor and the long standing JDK bug that are the cause resulting in

java.beans.IntrospectionException: type mismatch between read and write methods
