hould be a subset of the servers in the host list of the connection URL) are contacted in the order they are listed until a server is available or until the list of

for details. (Bug #20182108)
Bugs Fixed
* Secure JDBC connections did not fall back to the default truststore when a custom one was not provided. (Bug
#26243128)
* Connector/J failed a number of regression tests in the testsuite related to geographic information system (GIS)
functions because of changes to GIS support by the MySQL server. The fix corrects the tests. (Bug #26239946, Bug
#26140577)
* Attempts to connect to a server started with collation utf8mb4_de_pb_0900_ai_ci resulted in null pointer exceptions. (Bug #26090721)
* In com/mysql/jdbc/ServerPreparedStatement.java, the arguments resultSetType and resultSetConcurrency for a call of Connection.preparedStatement() were swapped
#25874048, Bug #85885)
* A NullPointerException was returned when getDate(),
getTime(), or getTimestamp() was called with a null Calendar. This fix makes Connector/J throw an SQLException in the case. (Bug #25650305)
* Some JDBC proxied objects were missing the proper handling of the equals() methods, thus even comparison of one of these proxied objects to its own self with
e. This patch introduces proper handling for the equals() method in all the relevant proxies. (Bug #21931572, Bug #78313)
* A server-side prepared statement was not closed when the same statement was being prepared again while the original statement was being cached. This was cause
cement of the cache entry of the old statement by the new. When this happened repeatedly, it caused eventually the complaint that max_prepared_stmt_count was exceede
e that when a cache entry for a statement replaces an older one, the older statement is immediately closed. (Bug
#20066806, Bug #74932)
