NPE in ResultSetImpl.next() using tomcat jdbc pool
Hello,
I've been trying to figure this problem out for some time now and I'm
totally stuck. The Exception in question is the following:
Caused by: java.lang.NullPointerException
at com.mysql.jdbc.ResultSetImpl.next(ResultSetImpl.java:7009)
at
com.server.persistence.state.connectors.jdbc.JDBCCleanupStateConnector.getUUIDsByTable(JDBCCleanupStateConnector.java:140)
... 8 more
It occurs very infrequently (and unfortunately I have not been able to
reproduce it yet). I have also checked all occurences of getConnection().
Every one of them is wrapped (like below) by try {} finally {if (con !=
null) con.close();}. Connections are not stored locally and used by other
threads later as far as I can tell either.
The last time this problem occured, the thread in question was actually
stuck for 10 minutes (as far as I reconstruct) before the NPE was thrown.
During this time, the thread was seemingly stuck on
SocketInputStream.socketRead0 (see below for stack trace), even though I
set the sockettimeout when creating the db pool.
Best regards
Henning Rohlfs

Looks like a bug in Connector/J. Are you up-to-date?
It occurs very infrequently (and unfortunately I have not been able
to reproduce it yet). I have also checked all occurences of
getConnection(). Every one of them is wrapped (like below) by try
{} finally {if (con != null) con.close();}. Connections are not
stored locally and used by other threads later as far as I can tell
either. The last time this problem occured, the thread in question
was actually stuck for 10 minutes (as far as I reconstruct) before
the NPE was thrown. During this time, the thread was seemingly
stuck on SocketInputStream.socketRead0 (see below for stack trace),
even though I set the sockettimeout when creating the db pool.
The connection pool probably gave-up on the connection and possibly
closed it. In that case, calling ResultSet.next() might have confused
Connector/J's implementation because the ResultSet should have been
killed by then.
@Override public ListString getUUIDsByTable( final String table)
throws TableNotFoundException { Connection connection = null; try
{ connection = stateDbIo.getConnection(); final PreparedStatement
ps = connection.prepareStatement( SELECT uuid FROM ` + table+ `
GROUP BY uuid ); final ResultSet rs = ps.executeQuery(); final
ListString result = new ArrayListString(); while ( rs.next() )
{ //this is where the exception is thrown result.add( rs.getString(
UUID_COLUMN ) ); } return result; } catch ( final Exception e ) {
throw new TableNotFoundException( table, e ); } finally { if (
connection != null ) { try { connection.close(); } catch ( final
SQLException e ) { // ignore } } } }
Don't forget to close your PreparedStatement and ResultSet objects.
Yes, I know that the JDBC spec says that closing the Connection should
close the associated objects (i.e. statement, result set), but in a
pooled situation, sometimes the JDBC specs break down a bit and
drivers (and pools) don't always follow things to the letter.
I'm using the tomcat jdbc database pool (7.0.42) to get the
connections.
stateDbIo.getConnection(): public Connection getConnection() throws
SQLException { if ( dataSource != null ) { final Connection
connection = dataSource.getConnection(); connection.setReadOnly(
readOnly ); connection.setAutoCommit( true ); return connection; }
It would be better to set the read-only and auto-commit flags based
upon the defaultAutoCommit and defaultReadOnly attributes of the pool
you configure. Then you don't have to worry about them ;)
I would guess that this is a MySQL Connector/J bug and not your fault.
That doesn't mean it's not your problem, though ;)
It sounds like you've done enough research to determine the problem
(timeout) so maybe you can create a small test-case that reproduces
it? I don't think it's got anything to do with Tomcat or tomcat-jdbc.
You should be able to rig-up a test case with a simple Java program
that connects to MySQL, then issues a long-running query (e.g. SELECT
SLEEP(10)) while the driver's timeout time is something less than 10
seconds. That should cause a disconnect during the query execution,
and subsequently calling ResultSet.next might fail.
Let us know how it goes.

Re: Issue while using SSL with Embedded Tomcat 6.0.37
Chris, On 10.10.2013 19:11, Christopher Schultz wrote: Also, Chirag has the connector supporting only TLS, so SSLv2 HELLO should indeally fail entirely. Setting attribute sslProtocol=TLS may actually enable all protocols from SSLv3 to TLSv1.2, plus SSLv2Hello. Even setting something like sslProtocol=TLSv1.1 would enable the same group of protocols. Tomcat docs clearly warns about that behavior (HTTP connector): sslProtocol - The the SSL protocol(s) to use (a single value may enable multiple protocols - see the JVM documentation for details). If you really only want to use TLS but support SSLv2 HELLOs, it's not entirely clear to me what setting you want here (sslEnabledProtocols), with sslProtocol, etc. I suspect what you want is this: sslProtocol=TLS sslEnabledProtocols=TLS, SSLv2Hello Chirag, give that a try and see if your problems are solved. That is not valid configuration. TLS is not legal value for attribute sslEnabledProtocols, and it will be ignored. SSLv2Hello is not legal without any other secure protocol so JSSE will throw an exception. Something like sslProtocol=TLS sslEnabledProtocols=SSLv2Hello,TLSv1,TLSv1.1,TLSv1.2 would be valid config for what you propose. It would also help to track down the cause of the problem, if Chirag sends handshake logs of failing and successful handshake. Also, a bit of a brainstorming now: could this whole thing be IP protocol issue? I've seen similar behavior before, albeit not in context of SSL handshake: client tries to connect using IPv6 address, but firewall doesn't allow it, so client falls back to IPv4 and successfully connects. -Ognjen - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Issue while using SSL with Embedded Tomcat 6.0.37
Hi All, Thanks a lot for your assistance. I enabled these protocols but that dint help. Finally after 24 hours of digging in I figured out the problem. We found out that the clients connection timeout was close to around 80mins(which is inexplicable) and there is a firewall in between the client and the server. After 60sec(server timeout) server sent a FIN to the client, but there is no ACK from the other side and server connection closes. So if the next request comes within 80mins it tries to use the connection which is in TIME_WAIT state,and thus fails since SSL handshaking is closed by the server. And second request onwards handshaking happens again. Appreciate all of you for your help. Chirag. Sent from Yahoo! Mail on Android
