NPE in Oracle 9.2.0.1 setTimestamp

Question

We recently encountered a situation where we got the following exception
java.lang.NullPointerException
at oracle.jdbc.dbaccess.DBData.clearItem(DBData.java:431)
at oracle.jdbc.dbaccess.DBDataSetImpl.clearItem(DBDataSetImpl.java:3528)
at oracle.jdbc.driver.OraclePreparedStatement.checkBindTypes(OraclePreparedStatement.java:3271)
at oracle.jdbc.driver.OraclePreparedStatement.setItem(OraclePreparedStatement.java:1133)
at oracle.jdbc.driver.OraclePreparedStatement.setTimestamp(OraclePreparedStatement.java:2274)
I decompiled the code for DBData.clearItem and found something kinda funny (see inline comments below)...
public void clearItem(int i)
if(m_dynamic && m_vector != null && i < m_vector.size())
m_vector.removeElementAt(i);
// Shouldn't this be
// if (m_items == null || i >= m_items.length)
if(m_items == null && i >= m_items.length)
return;
} else
m_items[i] = null;
return;
Is there anyone I should contact in particular about this problem? Especially since we will need to distribute some fix to our customers.
Thanks

Well, heres my test (10g, for I dont have a 9.2.0.1.0, but I think it´d show the same result):
Connected to:
Oracle Database 10g Enterprise Edition Release 10.1.0.4.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options

But he is getting output of table T2 too se his last postI don´t think so, because he didn´t SELECT it. Would be nice to just copy & paste the output...
