44 - Improved performance of ResultSetMetaData methods getPrecision(),
45 getScale(), isNullable() and isAutoIncrement(). The data is fetched
46 from the server by sending a query. This used to be one query for
47 each column of the ResultSet. Now these metadata queries are combined
48 into one query fetching this meta data for up to 50 columns in one query.
49 This reduces the number of queries sent to the server significantly.
50 This is noticable for instance when using generic JDBC query tools
51 such as SQuirreL, DBeaver, which now respond much faster.

58 - Implemented fix for released monetdb-jdbc-3.0.jre8.jar and
59 monetdb-mcl-1.19.jre8.jar when it is was run using java build 1.8.0_###.
60 It would throw:
61 java.lang.NoSuchMethodError: java.nio.CharBuffer.mark()Ljava/nio/CharBuffer;
62 at org.monetdb.mcl.parser.StartOfHeaderParser.getNextAsString(Unknown Source)
63 at org.monetdb.jdbc.MonetConnection$ResponseList.executeQuery(Unknown Source)
64 at org.monetdb.jdbc.MonetConnection$ResponseList.processQuery(Unknown Source)
65 at org.monetdb.jdbc.MonetStatement.internalExecute(Unknown Source)
66 at org.monetdb.jdbc.MonetStatement.execute(Unknown Source)
67 The problem is caused by a change in java.nio.CharBuffer API (return
68 types of methods mark() and reset() have changed from Buffer to
69 CharBuffer) from Java 8 to Java 9+.
