Description

When trying to set a font using CSPageContentStream.setFont() a new key is required which is created in PDResources.createKey(), ca line 450.

If the dict keySet contains "F1", "F2", "F4", "F5" then just trying to use

(dict.keySet().size() + 1)

will not find a new key und the loop won't terminate.

This here terminates:

        String key;
        int i = dict.keySet().size();
        do
        {
            i++;
            key = prefix + i;
        }
        while (dict.containsKey(key));
