Reports calls to java.lang.Runtime.exec() which take a dynamically-constructed string as the command to execute.

Constructed execution strings are a common source of security breaches. By default, this inspection ignores compile-time constants.

Example:

String i = getUserInput();
  Runtime runtime = Runtime.getRuntime();
  runtime.exec("foo" + i); // reports warning

Use the inspection settings to consider any static final fields as constant. Be careful, because strings like the following will be ignored when the option is enabled:

static final String COMMAND = "ping " + getDomainFromUserInput() + "'";
