Summary: IllegalArgumentException in WrappedResultSet
Initial Comment:
In JBoss 3.2.4 WrappedResult.getResultSet should return
null instead of trying to create a WrappedResultSet and
throwing an IllegalArgumentException when the rs is
null. It is legal to call stmt.getResultSet() when an
update count is returned and the result set would be
null (obviously the caller who does this checks the
return value). Here's a snippet:
String someSql = "update foo set bar=?";
Statement stmt = conn.prepareStatement(someSql);
// ... set parameters
stmt.execute();
// sometimes someSql is a query; if so do something.
if ((rs = statement.getResultSet()) != null)
{
/* do something */
}
produces a stack trace like:
java.lang.IllegalArgumentException: Null result set!
