I originally sent this to the users list but received no response. I'm really
hoping someone here can help me. Thanks in advance!
I'm running into this problem occasionally resulting in the exception below.
I'm using Jackrabbit 1.4 (with core at 1.4.2). I'm using the
H2PersistenceManager and almost all configuration values are set to their
released default. Document order is turned off so the query is using a
LazyScoreNodeIterator. I'm running in a transactional environment, and my
entire execution flow is contained by a single, read-only, JTA transaction.
The single transaction includes executing the query and all interactions with
the returned RowIterator. If I ignore the NoSuchElementException's and
continue using the iterator then there are often good results subsequent to the
error. I've noticed that when these errors occur there are often far more
results than are returned by RowIterator.getSize(). I realize that getSize()
is not meant to be an accurate count of all results, but in most other cases
getSize() is greater than the size of the result set (this may not be helpful).
I'm using a SQL query that involves the CONTAINS constraint (so lucene) and
ordering by jcr:score. Does this warrant a bug submission? Is there any
additional information which might help?
