setFetchSize() fails in getAllNodeIds()
---------------------------------------

                 Key: JCR-3090
                 URL: https://issues.apache.org/jira/browse/JCR-3090
             Project: Jackrabbit Content Repository
          Issue Type: Bug
            Reporter: Jukka Zitting
            Priority: Minor


I get the following exception from the PersistenceManagerIteratorTest on Windows:

org.apache.jackrabbit.core.state.ItemStateException: getAllNodeIds failed.
        at org.apache.jackrabbit.core.persistence.pool.BundleDbPersistenceManager.getAllNodeIds(BundleDbPersistenceManager.java:1043)
        at org.apache.jackrabbit.core.data.PersistenceManagerIteratorTest.testGetAllNodeIds(PersistenceManagerIteratorTest.java:106)
Caused by: java.sql.SQLException: Invalid parameter value '10'000' for Statement.setFetchSize(int
rows).

        at org.apache.jackrabbit.core.persistence.pool.BundleDbPersistenceManager.getAllNodeIds(BundleDbPersistenceManager.java:1020)

It's caused by the following code in ConnectionHelper when 0 < maxRows < 10000:

            stmt.setMaxRows(maxRows);
            stmt.setFetchSize(10000);

A simple fix would be:


            stmt.setMaxRows(maxRows);
            stmt.setFetchSize(Math.min(10000, maxRows));
