TIOBE - Java Coding Standard

Rule: SecurityCodeGuidelines2

This rule is Obsolete
Synopsis:	User-supplied arrays should be copied before use
Language:	Java
Severity Level:	2
Category:	SecurityCodeGuidelines

Description:

Constructors and methods receiving arrays should clone objects and store the copy. This prevents that future changes from the user affect the internal functionality.

public class Foo {
 private String [] x;
  public void foo (String [] param) {
      // Don't do this, make a copy of the array at least
      this.x=param;
  }
}
