> I tried to add an additional substitue mapping however it throws an exception:
> {code:java}
> java.lang.UnsupportedOperationException
>  at java.util.AbstractList.add(AbstractList.java:148)
>  at java.util.AbstractList.add(AbstractList.java:108)
>  at org.apache.pdfbox.pdmodel.font.FontMapperImpl.addSubstitute(FontMapperImpl.java:210){code}
> => Thus the addSubstitute() method is useless
> The reason is that for instantiating the mapping only a skeleton list from "Arrays.asList()" is used. This list doesn't support many methods of List interface and throws the exception.
> +*Solution:*+
> Replace the " Arrays.asList()" with the real list like new ArrayList() or the like.
