Hello Alex,
I'm not sure and as John indicated that this report and fix is required
in this forum. The code example provided below works fine when used directly
with a 9.4.1 server installation and 9.4-1200.jdbc4. This was just recently
demostrated in this forum for meta data on CallableStatements.
The only difference is the FUNCTION rather then your PROCEDURE definition/
call.

Complete Workable Code Sample Method.
public void test(Connection connection)
{
// Method Instances
String sqlStatementString;
Statement sqlStatement;
CallableStatement cstmt;
try
{
sqlStatement = connection.createStatement();
sqlStatementString = "CREATE OR REPLACE FUNCTION sum_n_product(x int,
y int, OUT sum int, OUT prod int) AS $$"
+ " SELECT (x + y) AS sum, (x * y) AS prod; $$ LANGUAGE SQL;";
System.out.println(sqlStatement);
sqlStatement.execute(sqlStatementString);
// Execute Function.
cstmt = connection.prepareCall("{call sum_n_product(?,?,?,?)}");
cstmt.registerOutParameter(3, Types.INTEGER);
cstmt.registerOutParameter(4, Types.INTEGER);
cstmt.setInt(1, 2);
cstmt.setInt(2, 5);
cstmt.execute();
int x1 = cstmt.getInt(3);
int x2 = cstmt.getInt(4);
System.out.println("x1: " + x1);
System.out.println("x2: " + x2);
// Drop Function.
sqlStatementString = "DROP FUNCTION sum_n_product(int, int, OUT int,
OUT int);";
System.out.println(sqlStatementString);
sqlStatement.execute(sqlStatementString);
cstmt.close();
sqlStatement.close();
}
catch (SQLException sqle)
{
System.out.println("SQL Exeception" + sqle);
}
}
