Vladimir Schneider commented on DOXIA-554:
------------------------------------------
I encountered a show stopper. Doxia requires Java6 compatibility and
flexmark-java requires Java7.
I converted the source to Java6 but BitSet in JDK7 is missing some BitSet
methods. Additionally, org.nibor.autolink used by the autolink extension is
byte code level 7 not 6.
The missing BitSet methods I can get around but the byte code level of the
autolink dependency would require rewriting the extension without the library.
Considering that JDK6 has reached EOL in 2012 is there a good reason why Doxia
is still requiring JDK6 compatibility?

> The parsing time for Markdown documents can take very long and hang site
> generation when e.g. long tables are being generated.
> The author of pegdown has marked the pegdown project deprecated since
> 2016-12-14 [pegdown.org|https://github.com/sirthias/pegdown/] and advises to
> switch to [flexmark-java|https://github.com/vsch/flexmark-java].
> {quote}
> The project is essentially unmaintained with tickets piling up and crucial
> bugs not being fixed.
> pegdown's parsing performance isn't great. In some cases of pathological
> input runtime can even become exponential, which means that the parser either
> appears to "hang" completely or abort processing after a time-out.
> {quote}
> Since the parsing timeout was increased in DOXIA-498 it is now possible to
> "hang" the site creation with a longer table like the one in this example.
> In case this sample is rendered using version 3.3 of the maven site
