annotate src/main/java/nl/cwi/monetdb/jdbc/MonetStatement.java @ 295:003ae6d881db

Add "final" keyword to method arguments and local variables where possible. It discovered some bugs in the MonetStatement constructor (changed the argument instead of object variable) which are fixed now. See also https://en.wikipedia.org/wiki/Final_(Java)
