Patrick Hunt commented on ZOOKEEPER-790:

I believe the problem found by Travis is a bug in the build for 3.3.1. If you 
d/l the latest release, patch it, and run "ant jar" this is included into the 

     [java] All version-related parameters must be valid integers!
     [java] Exception in thread "main" java.lang.NumberFormatException: For 
input string: "2-dev"
     [java]     at 
     [java]     at java.lang.Integer.parseInt(Integer.java:458)
     [java]     at java.lang.Integer.parseInt(Integer.java:499)
     [java]     at 
     [java] Java Result: 1

the build doesn't fail as the generated Version.java exists in the release, as 
a result you get the original Version.java, and therefore the old date.

You can see this better by doing a "ant clean jar", which will fail as the 
Version.java is cleaned by running ant clean. You can get around this
problem by running "ant -Dversion=3.3.2 clean jar" (a valid version string), 
after which you should see the current date in the log.

I'll fix this in the next rel.

> The leader code is setting the last processed zxid to the first of the new 
> epoch even before connecting to a quorum of followers. Because the leader 
> code sets this value before connecting to a quorum of followers 
> (Leader.java:281) and the follower code throws an IOException 
> (Follower.java:73) if the leader epoch is smaller, we have that when the 
> false leader drops leadership and becomes a follower, it finds a smaller 
> epoch and kills itself.
