Vladimir Schneider commented on DOXIA-554:
------------------------------------------

I was referring to maven-doxia version. The pom.xml for maven-doxia has:

{noformat}
<groupId>org.apache.maven.doxia</groupId>
<artifactId>doxia</artifactId>
<version>1.7</version>
<packaging>pom</packaging>
{noformat}
Changing the JDK version for the module is not a problem. I don&rsquo;t know 
how to direct the PR towards the right maven-doxia version since GitHub mirror 
only has the trunk version 1.7

The [git://git.apache.org/maven-doxia.git|git://git.apache.org/maven-doxia.git 
is exactly the same as the GitHub repo.

BTW, the change of the Markdown module to flexmark-java, with Java language 
level 1.7, is complete and passing tests. The only hitch is what version to 
assign to it and figuring out where to commit the changes an generate a PR.

> 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
