      Use an @NotNull or @RequiresNonNull annotation on a method to generate a null check and throw, by default, an IllegalArgumentException if null. Also clean the stack trace.

      Example Interface
      @Message(id = 123, value = "Name cannot be null")
@NotNull(IllegalArgumentException.class)
void requireNotNull(String name);
      Example Generated Code
      @Override
public void requireNotNull(final String name) {
    if (name == null) {
        final IllegalArgumentException result = new IllegalArgumentException(String.format(invalidUser$str(), name));
        final StackTraceElement[] st = result.getStackTrace();
        result.setStackTrace(Arrays.copyOfRange(st, 1, st.length));
    }
}

      The @Param annotation could be used along with @Pos for formatting possibly.
