Jukka Zitting commented on TIKA-642:
------------------------------------
No good alternatives until someone finds (or creates) a liberally licensed RTF
parser library that we could use instead of relying on javax.swing. Until that
the best we can do is to try add extra tweaks and hacks like the ones we
already have in the RTFParser class.
As a minor improvement on this, in revision 1124702 I added code that converts
such parse errors from IO- to TikaExceptions so we get a better error message
than the generic "Illegal IOException".
