Subclassing BaseParser?

[Allison, Timothy B.]

All,

  I'm probably suffering from the same failure that led to 
(https://issues.apache.org/jira/browse/TIKA-1678?focusedCommentId=14640370&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14640370),
 but is it possible to subclass BaseParser outside of the oap.pdfparser package?

  The actual subclassing of BaseParser is no problem, but what can I substitute 
for SequentialSource, given that it and RandomAccessSource are package-private?

  Thank you.

  Best,

             Tim
