error is thrown at constructor level only so no way to use any method on
the object of wordDocument or hwpfdocument.

Encrypted documents, POI just tries to parse them as normal ones.  What
you're seeing here is some size value which has been encrypted, and the
encrypted value is enormous, hence the OutOfMemoryError.

The workaround is simple enough: if the document is encrypted, don't try
to read in its text.
