I have an interesting stack trace reported from the udig-users list
java.lang.NullPointerException

Hunting down the code it appears as:
JDBCTransactionState tstate = (JDBCTransactionState) t.getState(this);
if(tstate != null) {
return tstate.cx;
} else {
Connection cx = createConnection();
try {
cx.setAutoCommit(false); /// <---- ERROR OCCURS HERE
} catch (SQLException e) {
throw (IOException) new IOException().initCause(e);
}
tstate = new JDBCTransactionState(cx, this);
t.putState(this, tstate);
return cx;
}
So it looks like createConnection() is failing; and returning null rather then
an exception?
Looking at the implementation it is mostly a direct call to datasource
getConnection(); is there any reason why that would return null for postgis?
