> }
> DbSetup.java:
> if (e.getMessage().equals(null)) {
> System.out.println("NULL error message detected");
> System.out.println("Here is the NULL exection - " + e.toString());
> System.out.println("Stack trace of the NULL exception - ");
> e.printStackTrace(System.out);
> }
> DbUtil.java:
> if (e.getMessage().equals(null)) {
> System.out.println(getThreadName()
> + " dbUtil --> NULL error message detected");
> System.out
> .println(getThreadName()
> + " dbUtil --> Here is the NULL exection - "
> + e.toString());
> System.out.println(getThreadName()
> + " dbUtil --> Stack trace of the NULL exception - ");
> e.printStackTrace(System.out);
> }
> If getMessage() returns null, the null checks will throw a NullPointerException instead of evaluating to true.
