Jason Lowe commented on YARN-8338:
----------------------------------
Thanks for the patch! Yeah, this looks like a case of a hidden dependency that
isn't getting pulled in.
I was wondering why we have to explicitly add this dependency when I can find
no use of objenesis in the code base. However I did notice this in the same
applicationhistoryservice pom that is being modified:
{code}
<dependency>
<groupId>de.ruedigermoeller</groupId>
<artifactId>fst</artifactId>
<version>2.50</version>
<exclusions>
<exclusion>
<groupId>org.javassist</groupId>
<artifactId>javassist</artifactId>
</exclusion>
<exclusion>
<groupId>org.objenesis</groupId>
<artifactId>objenesis</artifactId>
</exclusion>
</exclusions>
</dependency>
{code}
The explicit exclusion of the objenesis dependency looks like it could be the
reason we're not getting what we need. Does it make more sense to remove that
exclusion rather than add a dependency we're not directly depending upon?

implies we're not supposed to be using it in practice but apparently are.
