_Problem_
There is an error in the Error frame, the error codes used for
APPLICATION_ERROR,CONNECTION_ERROR,REJECTED,CANCELEDandINVALIDwere invalid._Solution_
Update the constants.
I don't think it requires doing any version bump, since the error code was not used
prior to #150.
_Modification_
I also took the oportunity to review the
framepackage and update it to the Javacode style.
