Spymemcached 2.8.0 not compatible with Hibernate-Memcached 1.2.2

[GoogleCodeExporter]

We are currently running spymemcached 2.7.3 with Hibernate-Memcached 1.2.2. 
When I tried to upgrade our JAR to 2.8.0 I am seeing the following error:

java.lang.NoSuchFieldError: NATIVE_HASH
        at com.googlecode.hibernate.memcached.spymemcached.SpyMemcacheClientFactory.getHashAlgorithm(SpyMemcacheClientFactory.java:125)
        at com.googlecode.hibernate.memcached.spymemcached.SpyMemcacheClientFactory.buildDefaultConnectionFactory(SpyMemcacheClientFactory.java:60)

This actually looks to have something to do with HashAlgorithm now being an 
interface

I agree. We changed the hash algorithm code in 2.8. It appears to me though 
that this should be patched in your code as opposed to ours. Either way without 
seeing some of your code I can't tell what the best way to fix this is.

It is not my code it is the Hibernate Memcached project.  

http://code.google.com/p/hibernate-memcached/

This is also broken in the latest version 1.3

Thanks, I'll try to contribute a patch to that project to get this fixed.

That would be great. Thanks!

I have written a patch in the hibernate memcached client for a temporary fix 
but I think the true solution is to make a patch so 2.8.0 is backward 
compatible hibernate-memcached.  Cheers.

can you post the solution here?

I am facing the same problem. I am using the latest hibernate-memcached 
(downloaded src and built from the git repo) and spymemcached-2.8.0.jar and I 
see similar errors as mentioned below.

Errors I see

nested exception is org.springframework.beans.factory.BeanCreationException:

You would need to replace this file in your hibernate memcached jar and 
rebuild.  Let me know how it goes.

With the new code in there is an issue. The latest hibernate-memcached 
(1.4.0-SNAPSHOT) depends on spymemcached 2.7.1 and compiles fine but a as soon 
as we replace the SpymemcacheClientLibrary with the one attached above and 
replace the dependency in pom.xml to spymemcached 2.8.0, I see the following 
errors

its kinda weird on why it would give errors for javax.jms related stuff. If 
anyone knows this. This would be helpful. I am going to post a question on 
hibernate-memcached project too. 

Thanks for the help!!

The dependency problem is due to how log4j describes dependencies.  You can 
specifically exclude the javax.jms and other transitive dependencies from log4j 
you're not actually using and then it'll be fine.

Note, the transitive dependency fix is in 2.8.1
