Seems to be jaxb issue with the default-firebird-encodings.xml

SEVERE [org.firebirdsql.encodings.DefaultEncodingSet]: Error loading encoding definition from default-firebird-encodings.xml
javax.xml.bind.JAXBException: ClassCastException: attempting to cast jar:file:/usr/share/netbeans-nb-8.2/ide/modules/ext/jaxb/api/jaxb-api.jar!/javax/xml/bind/JAXBContontext.class to jar:file:/opt/oracle-jdk-bin-1.8.0.121/jre/lib/rt.jar!/javax/xml/bind/JAXBContext.class.
