'instanceof' on 'catch' parameter

Reports cases in which an instanceof expression is used for testing the type of a parameter in a catch block.

Testing the type of catch parameters is usually better done by having separate catch blocks instead of using instanceof.

Example:

void foo(Runnable runnable) {
  try {
      runnable.run();
  } catch (Throwable throwable) {
      if (throwable instanceof NoClassDefFoundError) { // warning: 'instanceof' on 'catch' parameter 'throwable'
          System.out.println("Class not found!");
      }
  }
}
