Ankit Kumar commented on METAMODEL-233:
---------------------------------------
Debugged this issue further and what we see is that the query rewriting somehow
changes the SelectItem used in preparing the query. What we noticed is that the
"_query" element inside the SelectItem holds a completely different query than
the original submitted query and hence the ArrayIndexOutOfBound.
It goes wrong in the below code snippet inside SelectItem.java (clone) method.
final SelectItem subQuerySelectItem = (_subQuerySelectItem == null ? null :
_subQuerySelectItem.clone());
final FromItem fromItem;
if (_fromItem == null) {
fromItem = null;
} else if (clonedQuery != null && _query != null) {
final int indexOfFromItem =
_query.getFromClause().indexOf(_fromItem); // Goes wrong here Line 600.
if (indexOfFromItem != -1) {
fromItem = clonedQuery.getFromClause().getItem(indexOfFromItem);
Because the cloning somehow changes the original SelectItems used in query
preparation, it starts fails with this error for subsequent queries where we
use the same SelectItem objects.
