Hello All,

I am running Eclipse 3.1, eclipse.buildId=I200411050810, java.version=1.5.0

I realize that this maybe an Eclipse problem. My question: Is there
anything wrong with my getIPAddresses() method construction?

When I uncomment the following:
// List list = new LinkedList(); // Doubly-linked list
// list = new ArrayList();

I receive the error: 'An internal error occurred during: "Java AST
creation"'.

Here are the two lines in context of the target method:
_______________________________________________________________________________
     protected static LinkedList getIPAddresses(String sqlExpression) {
         sqlStatement = null;
         resultSet = null;
         List list = new LinkedList(); // Doubly-linked list
         list = new ArrayList();
         try {
             sqlStatement = MemConnection.createStatement();
             resultSet = sqlStatement.executeQuery(sqlExpression);
             while (resultSet.next()) {
                  list.add(resultSet.getString(1));
             }
         } catch (SQLException e) {
             AppError.errorMessage(e);
         }
         return (list);
     }
_____________________________________________________________________________

Here is the accompanied NullPointerException:
