Re: NPE in creating a SQLException

Peter

Can you send more code? Is "s" initialized in your synchronized block? You might print s before the synchronized block to verify... It could be your null pointer is there...

The offense starts here (SQLException:103)

if (!(this instanceof SQLWarning)) {
if (DriverManager.getLogWriter() != null) {
printStackTrace(DriverManager.getLogWriter());
}
}

And then continues on to (Throwable:509)

synchronized (s) {
s.println(this);
StackTraceElement[] trace = getOurStackTrace();

It is the "s.println(this)" that is causing errors... All of this is
happening in the constructor, so I guess that is why 'this' is null?
I'm not 100% sure and pretty confused by it all :/
