> In the constructor org.apache.pdfbox.cos.COSName.COSName(String, boolean), the field COSNam.hashCode becomes initialized after the COSName instance has been added to the cache.
> Thus, concurrent threads using the cached instance may see different values in COSName.hashCode().
>  
> Just to mention, that's another problem:
>  The whole caching is quite dirty, because it leaks memory if the application is not aware of calling COSName.clearResources().
>  Ideally, the class COSName would not exist at all, since it has no benefit over using strings directly. Of course, it would be quite a hard work to get rid of it.
