happening on the error handling flow, too. Although not universally loved/used, exceptions are a powerful mechanism of maneuvering execution on the unhappy path. Even if std::exception and related machinery happens when an exception occurs, both at the application level and the OS level. We'll explore the unwind process, the compiler generated code, the CRT hooks available and other exception internals. As We'll poke into these mechanisms and see how we can leverage them in our application error handling. Did I mention threads? Routing exceptions between threads... oh my! ## S Advanced Installer

integrate JDBCException message into Spring DataAccessException * SessionFactoryUtils keeps nested exception even case in case of TransientObjectException/PersistentObjectException * fixed HibernateSessionFactoryUtils Transaction * refined DataAccessUtils' "requiredUniqueResult" method to not throw an exception in case of a single null element Package org.springframework.jdbc * added InvalidResultSetAccessException errors too * changed SimpleMappingExceptionResolver's "exceptionMappings" to support exception patterns (similar to rollback rules) * changed SimpleMappingExceptionResolver's "mappedHandlers"

delimiter used in the placeholder. The default placeholder /opt/anaconda1anaconda2anaconda3 is an exception, being replaced with the install prefix using the native path delimiter. On Windows, the placeholder 2 is incapable of handling Unicode properly, especially on Windows. In this case, if any character in your PATH env. var contains anything that is not ASCII then you see this exception. ## Solution Remove adopted. (#13517 via #13520) • Interpret missing Cache-Control header as max-age=0 instead of exception. (#13522) ## Deprecations • Mark conda_env/cli/common as pending deprecation. Use conda.cli.common
