NPE in creating a SQLException

I'm getting the below NPE:

java.lang.NullPointerException
at java.io.PrintWriter.write(PrintWriter.java:247)
at java.io.PrintWriter.print(PrintWriter.java:392)
at java.io.PrintWriter.println(PrintWriter.java:529)
at java.lang.Throwable.printStackTrace(Throwable.java:509)
at java.sql.SQLException.<init>(SQLException.java:103)

org.postgresql.util.PSQLException.<init>(PSQLException.java:19)

org.postgresql.jdbc1.AbstractJdbc1Connection.ExecSQL(AbstractJdbc1Connec
tion.java:461)
at
org.postgresql.jdbc1.AbstractJdbc1Connection.setAutoCommit(AbstractJdbc1
Connection.java:942)

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 :/
