The type hierarchies for java.io.InputStream, java.nio.channels.Channel, javax.activation.DataSource and javax.sql.rowsel.BaseRowSet are now blacklisted as well as the individual types com.sun.corba.se.impl.activation.ServerTableEntry, com.sun.tools.javac.processing.JavacProcessingEnvironment$NameProcessIterator, sun.awt.datatransfer.DataTransferer$IndexOrderComparator, and sun.swing.SwingLazyValue. Additionally the internal type Accessor$GetterSetterReflection of JAXB, the internal types MethodGetter$PrivilegedGetter and ServiceFinder$ServiceNameIterator of JAX-WS, all inner classes of javafx.collections.ObservableList and an internal ClassLoader used in a private BCEL copy are now part of the default blacklist and the deserialization of XML containing one of the types will fail. You will have to enable these types by explicit configuration, if you need them. For Debian 9 stretch, these problems have been fixed in version 1.4.11.1-1+deb9u2. We recommend that you upgrade your libxstream-java packages.
