Marc Campbell commented on DOXIA-554:
-------------------------------------
My workaround for this issue has been to use a hybrid solution of
doxia-module-markdown (pegdown) and vsch/markdown-page-generator-plugin
(flexmark-java).
Such a hybrid is implement in the following project:
--> https://github.com/marc-medley/004.55.markdown-maven-plugin-eval
The project uses a header.html and foot.html based on doxia-module-markdown
generated html to wrap content html generated from
vsch/markdown-page-generator-plugin (flexmark-java).
Thus, doxia-module-markdown provides project reports, while
vsch/markdown-page-generator-plugin (flexmark-java) converts the markdown pages
which need something better than pegdown.
The real fix would be to have pegdown replaced in the doxia-module-markdown
plugin.

> 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].

> 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
