V6054. Classes should not be compared by their name.

The analyzer has detected class comparison by name. Such comparison is considered incorrect since, as stated by the JVM specification, classes have unique names only inside a package.

In addition to logical errors, such code may sometimes get exposed to various vulnerabilities due to unknown behavior of an untrusted class.

Consider the following example:

if (obj.getClass().getSimpleName().equals("Plane"))
{
  ....
}

This code should be rewritten as follows:

if(obj.getClass().equals(ArrayList.class))
{
  ....
}

or:

if (obj instanceof Plane)
{
  ....
}

or:

if (obj.getClass().isAssignableFrom(Plane.class))
{
  ....
}
