Hi,
I just upgraded to .111 and there seems to an issue where a null
pointer exception is thrown.
I create the connection using:
// Create conn...
JdbcDataSource dsl = new JdbcDataSource();
dsl.setURL(debugURL = "jdbc:h2:"+dbDir+"/emoa-
encrypted;CIPHER=AES;WRITE_DELAY=2000;LOCK_TIMEOUT=2500");
dsl.setUser(debugUser = "sa");
dsl.setPassword(xxx);
// Bind to JNDI so I can look it up from TopLink.
System.setProperty(Context.INITIAL_CONTEXT_FACTORY,
SimpleNamingContext.Factory.class.getName());
SimpleNamingContext.Factory.setContext(new
SimpleNamingContext());
InitialContext ic = new InitialContext();
ic.createSubcontext("jdbc");
ic.bind("jdbc/MidwifeMateDS", dsl);
When I step through it slowly in the debugger, the error does not
occur. But when I break on null pointer exception, I catch a null
pointer exception in:
/**
* INTERNAL
*/
public JdbcConnection(JdbcConnection clone) {
this.session = clone.session;
trace = session.getTrace();
int id = getNextId(TraceObject.CONNECTION);
setTrace(trace, TraceObject.CONNECTION, id);
this.user = clone.user;
this.url = clone.url;
}
On the line where it is calling "session.getTrace()". Pretty much
everything in the session seems to be null, and higher in the stack
trace it looks like it's creating a new connection within the
connection pool. This worked in .108, however the SELECT...ORDER BY
was causing me greif so I upgraded.
Thanks, Y.
