The job config in this case is
<scm class="hudson.plugins.mercurial.MercurialSCM">
<installation>default Mercurial with caching</installation>
<source>http://hg.netbeans.org/main-silver/</source>
<modules></modules>
<clean>false</clean>
<forest>false</forest>
<browser class="hudson.plugins.mercurial.browser.HgWeb">
<url>http://hg.netbeans.org/main-silver/</url>
</browser>
</scm>
but other jobs also fail as well. Possibly a problem with unserializable
anonymous classes being passed around in remoting.
