compilation failure and compilation error messages

Wed Apr 23 22:35:00 GMT 2003

I've been hacking the postgresql jdbc build to make it GCJ
friendly. The JDBC3 support seems to throw up a few problems with
3_3-branch.
The first is that package private stuff doesn't seem to be properly
implemented but I'll report that separately with a test case when I
have one.
The main problem I want to ask about involves a class quite deep in a
tree of subclasses.
Jdbc3RefCursorResultSet.java:
 public class Jdbc3RefCursorResultSet extends Jdbc3ResultSet 
 implements PGRefCursorResultSet
 {
	Jdbc3RefCursorResultSet(java.sql.Statement statement, 
 String refCursorName) 
 throws java.sql.SQLException
	{
 super(statement, null, null, null, -1, 0L, false);
 .
 .
 .
Jdbc3ResultSet.java:
 public class Jdbc3ResultSet extends org.postgresql.jdbc3.AbstractJdbc3ResultSet 
 implements java.sql.ResultSet
 {
 public Jdbc3ResultSet(BaseStatement statement, 
 Field[] fields, Vector tuples, 
 String status, int updateCount, 
 long insertOID, boolean binaryCursor)
 {
 super(statement, fields, tuples, status, 
 updateCount, insertOID, binaryCursor);
 }
 .
 .
 .
When compiling this I get this:
org/postgresql/jdbc3/Jdbc3RefCursorResultSet.java: In class `org.postgresql.jdbc3.Jdbc3RefCursorResultSet':
org/postgresql/jdbc3/Jdbc3RefCursorResultSet.java: In constructor `(java.sql.Statement,java.lang.String)':
org/postgresql/jdbc3/Jdbc3RefCursorResultSet.java:21: error: Can't find constructor `org.postgresql.jdbc3.Jdbc3ResultSet(Ljava/sql/Statement;VVVIJZ)' in type `org.postgresql.jdbc3.Jdbc3ResultSet'.
 super(statement, null, null, null, -1, 0L, false);
This is clearly wrong. However, what I really don't understand is
what the type specifiers in the error message mean:
 Ljava/sql/Statement;VVVIJZ
for a method call which should read:
 Statement, Object, Object, Object, int, long, bool
Now I and J look right for an int and a long but I was kinda expecting
Ls instead of Vs. Can anyone enlighten me to what the letters mean?
