Vulnerabilities Table of Contents

Description

It is generally a bad practice to catch NullPointerException.

Programmers typically catch NullPointerException under three circumstances:

  1. The program contains a null pointer dereference. Catching the resulting exception was easier than fixing the underlying problem.
  2. The program explicitly throws a NullPointerException to signal an error condition.
  3. The code is part of a test harness that supplies unexpected input to the classes under test.

Of these three circumstances, only the last is acceptable.

Risk Factors

TBD

Examples

The following code mistakenly catches a NullPointerException. 

	  try {
		mysteryMethod();
	  }
	  catch (NullPointerException npe) {
	  }
